My favorite trade yet!
Los Angeles Lakers - Incoming Players:
Dwyane Wade
Antoine Walker
Kevin Garnett
Outgoing Players: Andrew Bynum, Kwame Brown, Lamar Odom, Kobe Bryant
Laker rotation: Mihm, KG, Walton, DWade, DFisher; rotation subs Turiaf, Cook, AWalker, Radmanovic, Evans, Farmar/ Crittendon
A deep team, with a nice blend of youth and experience. Eating Walker's contract and losing Bynum is worth it to upgrade longterm at 2 and 4 and rid themselves of the Kobe headache. I could easily see this team threatening the Texas threesome and Phoenix for West supremacy.
Minnesota Timberwolves - Incoming Players:
Dorell Wright
Andrew Bynum
Jason Williams
Michael Doleac
Kwame Brown
2 Miami #1 picks
Outgoing Players: Kevin Garnett
Minny gets young prospects and expiring contracts and future picks. Just what they want for KG.
Miami Heat - Incoming Players:
Lamar Odom
Kobe Bryant
Outgoing Players:
Dorell Wright
Dwyane Wade
Antoine Walker
Jason Williams
Michael Doleac
Miami rotation: Shaq, Haslem, Odom, Kobe, Smush Parker (who already signed with them); rotation subs are Zo, Simien, Quinn, plus whomever else they sign with rest of midlevel…. if they could swing JC Navarro or some other decent PG with what's left of the exception, they could have the most fearsome starting 5 in the league, plus the best backup center in Zo. If they stay healthy, an obvious favorite to come out of the East and play in the Finals.

Faith and confirmation bias
It turns out that a reseracher at my alma mater, Emory University, named Drew Westen led a functional magnetic resonance imaging (fMRI) study that shows where in the brain the confirmation bias arises and how it is unconscious and driven by emotions. In Scientific American, Michael Shermer explains and expands upon the study, which revealed how the brain suppresses the rational, reasoning portion of the brain in favour of emotions that reinforce confirmation bias. As Shermer puts it:
"During the run-up to the 2004 presidential election, while undergoing an fMRI bran scan, 30 men--half self-described as "strong" Republicans and half as "strong" Democrats--were tasked with assessing statements by both George W. Bush and John Kerry in which the candidates clearly contradicted themselves. Not surprisingly, in their assessments Republican subjects were as critical of Kerry as Democratic subjects were of Bush, yet both let their own candidate off the hook.The neuroimaging results, however, revealed that the part of the brain most associated with reasoning--the dorsolateral prefrontal cortex--was quiescent. Most active were the orbital frontal cortex, which is involved in the processing of emotions; the anterior cingulate, which is associated with conflict resolution; the posterior cingulate, which is concerned with making judgments about moral accountability; and--once subjects had arrived at a conclusion that made them emotionally comfortable--the ventral striatum, which is related to reward and pleasure."
Westen's own summary went as follows:
"Essentially, it appears as if partisans twirl the cognitive kaleidoscope until they get the conclusions they want, and then they get massively reinforced for it, with the elimination of negative emotional states and activation of positive ones."
In other words, faith - in the form of confirmation bias - is emotionally rewarding and hence comfortable for us humans; seeking the truth, with its uncomfortable possibility (indeed, probability, for the usual human) that we could be wrong about what's important to us, that our foundational beliefs could be all wrong, that what our parents and society and pastors and friends have all proclaimed for years and years could all be wrong - no, it is most certainly not a recipe for short-term emotional well-being.
But in the long run, it's the truth, and nothing but the truth, that shall set us free - and so we must resist the soft seductions of faith. Advertisers, politicians and other charlatans take advantage of our limited rationality, with its confirmation bias and other cognitive imperfections - all these ways in which we are closer to the rest of the animal kingdom, rather than appealing to what is highest and best in us. If we last long enough, one day this too shall end - the truth shall set us all free.
IF we last long enough....

Unintelligent Design
The Biological Design Argument
1 Living things evince design
2 Design requires a designer
3 Life could not have designed itself
So a Designer of all life must exist - God
The problem: Natural selection and survival of fittest can explain apparent design without a conscious Designer - that is, random variation/ mutation, combined with nonrandom selection through differential death based on relative fitness, quickly "designs' organisms better and better fitted to their ecological niche, by making them more numerous and their lesser competitors less numerous. Hence, premise 2 (or 3, depending on an ambiguity in the term 'design') is false.
Logic, however rationally compelling, often leaves people cold. So let's use some examples to help. An omniscient and omnipotent and omnibenevolent Designer would create optimal designs (or else would lack at least one of those 3 attributes). So simply showing that biological organisms are suboptimally designed would refute the existence of such a designer.
One of the simplest examples of such suboptimal design is the very feature that traditional creationists often appealed to as evidence of god's ingenuity, the human eye. (And not only Christians are bewitched by the "irreducible complexity" of eyes - stupid Muslims use the same arguments.)
So how dare I impugn the optimality of the design of human eyes? Well, for starters, I'm typing this while wearing glasses. That alone should be plenty of evidence! But for those who need more argument, read the following wonderful synopsis:
That's right, the octopus and squid don't suffer from detached retinas or a blind spot as we poor humans are prone to; the positioning of their photoreceptors and blood supply also means they suffer from blurry vision and blindness less often as well, ceteris paribus. In short, our single most dominant sense, the one so dominant that an entire theory of knowledge (now convincingly argued to be false) depends on thinking of ideas as like visual images - that sense is suboptimally designed in comparison to another species alive right now. What kind of a fuck-up would've done that?
"The retina is the 'screen' at the inside back of each eyeball, onto which is projected the incoming light. It is made up of lots of photoreceptor cells with their associated out-going nerves, and the blood supply to them. The problem is, the photoreceptors are in backwards, pointing away from the incoming light: the 'cable' from each cell is therefore in the way, and trails across the eyeball's inside surface to exit the retina at the correctly-named 'blind spot'.
Now, the brain compensates for this, so we don't usually notice it. But a design that needs compensatory mechanism for some aspect of it, is not a good design.
But to make matters worse, this design actually causes unnecessary problems. The photoreceptors have delicate, hairlike nerve endings, which means they cannot be cemented firmly into place. Instead, they are loosely joined to a layer of cells called the retinal pigment epithelium. This absorbs stray photons that would otherwise blur the image, and contains the retina's blood supply. But the connection between the retina and the epithelium is so fragile that the retina can detach, either due to a blow to the head, or often, spontaneously. Starved of their blood supply, the retinal cells die, causing blindness.
Strangely, the creator was able to put retinas the 'right' way round... in those pinnacles of His purpose, the octupus and squid. Not only do their eyes, which are basically the same design as vertebrate ones, have their photoreceptors pointing towards the light, and so lack a blind spot; with the nerves training behind them and embedded in their blood supply, the cephalopod eye is far less prone to detached retinas."
The short answer: a satisficing historical process called evolution, not a perfect divinity. For those who like reality-based rather than faith-based thinking, it's time to let go of religion and embrace reality - our future may depend on it.

Arguments against the existence of God
Let's formalize this claim:
Argument from religious experience:
1 many people have religious experiences, which they interpret as experiences of God;
2 people’s own interpretations of their experiences are trustworthy;
thus, God exists.
The problems with this argument abound - here's a few: for premise 1, which tradition/ history of experience are we referring to? Different religions and different believer's claimed experiences make numerous conflicting/ contradictory claims, with many different incompatible theories of God proclaimed - leads to doubt that one single thing could be so multiply interpreted. At most one is right. If many are wrong, why not all?
Premise 2 is fairly obviously false - the mere having of religious experience obviously doesn’t guarantee God exists, or more to the point, guarantee that one is an accurate interpreter of one's own experience. We misunderstand what is happening to us all the time. Take, say, schizophrenia and the biblical story of Abraham and Isaac, in which God tells Abraham to kill his son... what would you say to someone who walks up to you on the street and tells you - 'God told me to kill my family'. Would you take that as proof of the existence of the divine? Or is a mental disorder a more likely (and more parsimonius) explanation?
Are there any other ways to explain religious experience other than real God? Yes –
Other arguments against existence of God - Let's start here by formalizing that first problem above:
Inductive argument from diversity of religious experience versus God:
1 many people have religious experiences, which they interpret as experiences of God, but their accounts conflict;
2 there are 10000-plus different religions, all relying on claimed experiences of the divine, all of which accounts conflict in at least some detail (or else they would be the same religion!);
3 hence, most religions and their claims about the experience of the divine are untrustworthy in at least some details about God, as at most one could be entirely right;
4 there is no rational way to decide that one faith-based claim about god is more defensible than any other (analytic, from the definition of faith)
5 hence, there is no rational reason to think any particular religion is more likely to be entirely correct than any other
6 But logic dictates that (almost) all religions make false claims about god – at most one could be correct - so (almost?) all religions make false claims about god
7 Given there’s no rational basis for choice and the vast majority are known to be false, then inductively, the only reasonable belief is that all religions and personal experiences are wrong about God - that indeed, all religions make false claims about god
5 Occam’s razor – so we don’t need true beliefs about God to explain religious belief
thus, God doesn’t exist.
Another argument versus God- Argument from Simplicity:
1 Occam’s razor/ principle of parsimony/ simplicity - don't multiply entities beyond necessity, don't believe in the existence of things that are not required for explanations
2 we don’t directly experience anything that corresponds to concept (definition) of God (cf apple, or the color orange)
3 we don’t indirectly experience anything whose best explanation is that it must be caused by God (cf electron, proton)
4 So God is not required to explain any experience we have
So no need for God’s existence – so by Occam’s razor, God doesn’t exist
And another - for the simplicity argument is connected to ‘God of the gaps’ argument:
1 we believe in a supernatural God because It explains what natural science cannot
2 so God’s attributes are traditionally given in terms of what science cannot explain – god is defined by the gaps in science
3 But the history of science shows that science progressively explains more and more things formerly attributed to God
4 Inductively, there’s no reason to think that science will not eventually explain everything that can be explained
5 So God explains nothing – and so has no attributes
So God does not exist
Compare the problem of evil (POE): argument against God from concept and consequences
1 God is 3 omnis (omnipotent, omniscient, omnibenevolent) and creator of the universe
2 Evil exists
3 God, if existing, would not allow evil (If God is 3 omnis, evil would not exist; i.e., God and evil are incompatible - (God would know how to, want to, and could prevent all evil).
Thus, God does not exist

I better publish soon...
Briefly, Gott's version hypothesizes that there is a 95% confidence level that we are in the middle 95% of the lifespan of any phenomenon we randomly observe. Manned spaceflight began 46 years ago, so Gott reasons there's a 50% chance it will end within 46 more years, and uses this as an explanation of the Fermi Paradox - we don't observe other alien civilizations because they never left their home planet. So Gott believes we need to colonize Mars, sooner rather than later, if we want humanity to have a long future.
My argument is a bit more sophisticated, but largely agrees with Gott's. More to come...

Are the Spurs the real champs?
Most of the people who believe in such a counterfactual history think the Game 5 suspensions of Amare Stoudemire and Boris Diaw were the key to the wrong team winning the Spurs-Suns series. Now, it turns out Game 3, with calls missed so badly that the play by play announcers had to comment, was called by... Tim Donaghy. As Bill Simmons points out, this is the league's nightmare, and it won't end any time soon. The reality that the league champ might be so through ref malfeasance was broached by Simmons in the 2006 Finals, and he now appears prescient. Unless David Stern manages to make the refs more accountable, their evaluation more transparent, and their temptation to cheat less profitable (presumably by paying them a great deal more), the league may have a credibility problem that will eventually make it the inferior of pro wrestling.

The poison of faith
When faced with morally bankrupt yet powerful forces of evil, angry invective is sometimes warranted. Christopher Hitchens is right about the vast majority of organized religion - it poisons everything - as he jeers that the Catholic motto should be "no child's behind left." Those who bid moral actions and cloak it in religious language are fooling themselves, and others, in ways that have repeatedly shown to be dangerous, because of the credulity and irrationality of the mass of humanity. Rational religion turns out to be an oxymoron, and the Brights realize this. But their influence, while growing, remains minuscule, and the danger increases far more rapidly.
So, I am exceedingly pessimistic about our future, because that credulity and irrationality - that faith - is increasingly tied to more and more potent weaponry, and ere long will be tied to Doomsday weaponry - most likely nanotechnology or bioweapons, I fear. Like the religious, I imagine Armageddon will happen soon (within 40-80 years), but without trumpets of Christ or Heaven - just death, for us all. And I expect that our collective demise will likely be brought about by those who think that Death brings us to a better place, as long as we believe their fantasies - and if we don't believe their fantasies, then they will make our lives a living Hell, for eternity - starting now. Even the most rational of the religions, Unitarian Universalism, refuses to abjure such fantasies entirely.
Religion indeed has similarities to an opiate, but its effect is far more insidious and harder to crack, because the addict will sober up periodically and realize their plight; whereas religion systematically disables the critical mentality needed to subvert it. It tells us faith is the key to morality, not the enemy of morality; that murder, torture, rape and pillage are fine if one's god so demands; and so on. The true enemy of religion is philosophy, in the broadest sense - the search for truth. Once that becomes your goal, you realize there is no need - indeed, no room - for faith; because faith, by its very nature, is inimical to a search for truth. Faith is belief without justification, without argument, without knowledge - faith is belief unsupported by the evidence. Only when one renounces such blandishments and seeks the truth and nothing but the truth, can one finally become free of the evil that is organized religion. So I must say I'm sorry to tell my friend Dan the apparently unwelcome news - for Dan blogs:
"Maybe my blogging friends will explore more deeply the psychological and philosophical implications of all of these matters (yes, SI and KA, if you’re reading this, that’s an invitation). For my part, I’ll just challenge you to go out and prove that the best antidote to bad religion is not no religion, but is in fact good religion."
I'm afraid I have to disagree that there is, in fact, any good religion. If our world can get to a place in which we can accept that ethics has no need of God, as contemporary philosophers like Derek Parfit and Kai Nelson argue, we will all be much better off. Hamas and Orthodox Jews cannot claim divine sanction for their mutual land grabs and murder - or Shia and Sunni in Iraq, or Protestant and Catholic in N. Ireland, or... the list never ends. But you cannot persuasively argue their wrongness by substituting their fantasy with some other one. You can only win that argument by rejecting fantasy for reality completely - by giving up every single jot and tittle, every minute iota of faith.
So, rejecting faith as a legitimate answer to any moral questions is one key to the human species having a long future. Again, sadly, I don't believe it will happen in time....
More to come. Civil comments welcome.

NBA conspiracy and other news
Speaking of which, it seems safe to officially drop Phoenix from the KG sweepstakes now - as reports that owner Robert Sarver mandated dropping $7 mil off payroll to avoid the luxury tax came true today, as they dealt the contract of Kurt Thomas to Seattle, plus 2 future first round picks, for a second-rounder next summer. The incentive for Seattle is obvious, given they're rebuilding; but Phoenix continues to deal away potential bench pieces and draft picks in an attempt to keep their top 6 together without paying the luxury tax. A KG trade is now essentially impossible under the salary cap, and certainly impossible if Sarver isn't willing to pay the tax. More and more I think there are only 3 possible destinations for KG this summer - Lakers, Dallas, and Miami. Most likely is that KG is still a T-wolf to open the season.
Finally, the conspiracy theorists have a field day today, with news that the FBI is going to charge NBA ref Tim Donaghy with point-shaving. Rumor (and let's be clear, only rumor at this stage) has it that he has a gambling problem, got in hock to the Mob, and shaved points in games he reffed to pay off his debts. What's a fact is that he was one of the refs at the infamous Brawl Game, and was a major figure in Rasheed Wallace's longest suspension. I haven't yet heard whether he was involved in any other of the most notorious playoff series in which ref bias is commonly alleged, like the Dallas-Miami 2006 Finals, or the Lakers-Sacramento 2002 Western Conference Finals, now best remembered for Robert Horry's winning 3-pointer at the buzzer in game 4.

Napa Valley A's?
Well, perhaps the lack of wine-lovers is not the cause of their demise, but the A's quest to find a new home might do better in Napa Valley than the current quest to relocate 25 miles south in the town of Fremont, in a development led by Internet networking business Cisco Systems. If they want to move upscale, why not associate with wine instead of routers?
As for me, let's see if I can find a Silver Oak cabernet for cheap now...

Nuclear doomsday breaking news
Putin obviously believes the West is encircling Russia with anti-ballistic missiles as preparatory to an attack, and is ratcheting things up. He believes Bush left behind the old logic of deterrence with his withdrawal from the ABM treaty and his ongoing attempt to build the 'Star Wars' missile defense, making America invulnerable (if it worked, which it doesn't). We have the increasing distrust that can lead to a major conflagration. If Bush gets us into a nuclear war with Russia, he really will have the worst President in history title - for eternity, perhaps.
Saturday, July 14, 2007
Nuclear doomsday, continued
Why? Because this US "counterforce" dominance changes the usual logic of deterrence. If China ever put its missiles on alert (say, over a brouhaha over Taiwan declaring independence, a scenario that appears increasingly likely over the next decade), the US military commanders quite conceivably would place almost insurmountable pressure on the US President to launch a first strike - because we could effectively wipe out China's nukes at one blow, and assure next to nothing from China would hit the mainland US - but only by striking first. If we waited for the Chinese to strike first, China could still be largely obliterated by a US counterattack, but many (most?) American cities would be incinerated. The old logic of the Soviet-American mutual deterrence through mutually assured destruction (MAD) no longer applies - with our new weapons and China's relative paucity of ICBMs, if tensions rise, the logical thing for the self-interest of the US to do would be to launch a preemptive strike that takes out all Chinese capabilities to attack the US mainland. If the Chinese know that, their logical course of action would be to launch a first strike as well, with no warning. After all, if they allow the US to strike first, they would certainly be obliterated.
If that isn't scary enough - consider: would Russia sit idly by as the US turned its southern neighbor into a smoking pile? Or, with a near-totality of US nukes headed to Chinese targets, would Russian missile command seize that chance to launch a third strike - against the US? It would no longer be quite so completely suicidal in the short term if the US had just used most or all of its arsenal on China, and given Russian paranoia and world-historical ambition, can one be sure they would not try? The resulting 3-way nuclear holocaust might be enough to cause the 'nuclear winter' that Carl Sagan foresaw in 1983, in a study that concluded: "...the possibility of the extinction of Homo Sapiens cannot be excluded."
Have another nice day!

An old model of Doomsday
The US and the Soviet Union were the only countries ever armed with enough weapons to plausibly cause a real worldwide Doomsday; and despite mutual reductions since the fall of the Soviet Union in 1991, both the US and Russia maintain nearly 6000 warheads (estimated) capable of use, with over 1000 on 'high alert', ready to fire within a few minutes. Both countries also have many more warheads in storage, capable of being hauled out and used within a relatively short period of time - the Russian estimate in storage is up to 16,000.
During Vladimir Putin's presidency, relations with the US have grown progressively frostier, with Putin in a speech on Victory Day (May 9th) rhetorically comparing the US to Hitler's Third Reich, and promising “The victory once again will be ours.” Perhaps even worse, at a conference in Munich on February 10th, Putin delivered a venomous speech directly addressed to an audience that included US defense secretary Robert Gates, Senator and Presidential candidate John McCain, as well as German Chancellor Angela Merkel and other international heavyweights.
In his February 10 speech, Putin asserted all of the following:
“Unilateral and frequently illegitimate actions [by the US] had caused new human tragedies and created new centres of tension.” [The world] is witnessing an almost uncontained hyper use of force, which was plunging it into an abyss of permanent conflicts. ... the United States has overstepped its national borders in every way, exhibiting a greater and greater disdain for international law."Putin then claimed that the US actions were the cause of a new arms race, and the cause of some countries acquiring weapons of mass destruction.
Despite such rhetoric, most observers think Russia is unlikely to launch a nuclear war with the US, and the US likewise will not launch a first strike on Russia. (Of course, how many of these same observers predicted the demise of the USSR in 1991? Kremlinology is a notoriously imprecise science). But there is a more fearsome scenario, in which Russia joins in a nuclear confrontation that it was not originally a part of - and such a three way nuclear war might actually cause Doomsday, or come close. The third party - China. More to come...
The sting of truth about the bees
But a far more reasonable - and less alarmist - piece compares the bees to cows, in that they occupy an artificial ecosystem and would've long ago been wiped out without intensive human care, and opines that their passing will be no big deal. Heather Smith points out that the varroa mite decimated native honeybee populations between 1987 and 1994 in the US, and farmers since have trucked the remaining bees around the country and doused them with antibiotics in order to keep them humming long enough to pollinate their crops. Yet such practices have done nothing to stop the incipient demise of the native honeybee, merely weakening it for whatever other pathogens are involved in CCD.
Smith further points out that the demise of domestic honeybees will hardly mean the end of agriculture, even the farming that currently relies on bee pollination:
...the California Almond Board two-timed the honeybee with osmia ligneria—the blue-orchard bee: Despite CCD, they had a record harvest.In short, much like the killer bee scare of two decades ago, in which we all "learned" that killer bees would unleash a spree of death by stings as they crossed the Rio Grande and made mincemeat of American flesh by massive attack and allergic reaction, the uproar over CCD is much ado about little. One should save the Doomsday talk for more realistic scenarios - some of which are to come...

Houston loads up...
What about Houston? Obviously they hope Scola can come to terms and give them some offense at the 4, as the trade of Juwan Howard for Mike James opened up an opportunity. And Butler looked promising a couple of years ago - who knows, he may still have something left. Houston's new GM looks like he may know what he's doing.... and the Rockets become an even more scary contender next season.

NBA free agent movement - it's NOT fantastic!
Chauncey Billups re-signed in Detroit, Rashard Lewis got an absurdly huge deal in Orlando, and as forecast, that resulted in Darko going elsewhere - to Memphis!? He and Gasol might co-exist on offense, but this doesn't help their interior D at all. Darko can block shots, though - they should definitely play zone D in Memphis next year and tell Darko to work on his jumper.
Other overpays: Luke gets way too many years in LA, Kapono's limitations will be revealed in Toronto (how is he an upgrade over MoPete?), Andres Nocioni gets a lot for his post-peak seasons in Chitown. It looks like Derek Fisher will return to LA, although if they're really going to pay him the midlevel (or close), then their decision to let him go years back (for the midlevel then!) was indefensible. Live and learn, eh, Dr Buss?
As noted, the main speculation left seems to be whether Mo Williams will take the midlevel for Miami, or if they have to go to their fallback, Steve Blake. No wonder teams are trying to preserve cap room for next summer - this summer's crop of free agents are hardly impressive. As things move along, it looks less and less likely that either KG or Kobe will be dealt before the season starts - though I do expect some terrible KG deal to occur close to the trade deadline next February. Even Isiah may have little left to do - especially if he isn't going to trade the only player other teams actually want, David Lee.
The other names outstanding and still available mostly consist of injured has-beens or never-wases (like Chris Webber, Stevie Francis (a Clipper to be?), or Chris Mihm) or prospects who have starred in Europe who may finally come over (Luis Scola, Juan Carlos Navarro). Honestly, the latter are more attractive than the former, but require trades - Scola's rights are owned by the Spurs, Navarro's by the Wiz. The Clips would be better off with Navarro than the self-deluded Stevie Franchise, but that's not the way they think....
So not much so far has occurred that would change the power structure of the end of last season. Roughly, the good teams should stay good, and the bad teams mostly haven't improved much - unless Darko suddenly erupts and turns Memphis back into a playoff team - pretty damn unlikely. And Orlando, despite a max contract for Rashard, probably remains what they were - a fringe playoff team in the East.

Outsourcing prayers to India
Purgatory has always been good business - remember those sales of indulgences, the ones that got Martin Luther hot under his clerical collar? I wonder how long governments will continue to ignore the fact that religion is a multi-billion dollar business, and should be regulated and taxed appropriately? Of course, like lots of big businesses, religions are quite skilled at lobbying governments to preserve their ability to use taxpayer dollars for their own purposes...

The Original Doomsday Argument
The simplest Doomsday Argument:
Physicist Richard Gott’s simple Copernican Principle proposes to compute prediction intervals for the future duration of any randomly observed phenomenon. Gott's method hinges on the "Copernican assumption" that there is nothing special about the particular time of your observation, so with 95% confidence it occurs in the middle 95% of the lifetime of the phenomenon. If the phenomenon is observed to have started A years ago, Gott infers that A represents between 1/40 (2.5%) and 39/40 (97.5%) of the total life. He therefore predicts that the remaining life will extend between A/39 and 39A years into the future. (Given Gott's assumptions, this is simple algebra: if A = (1/40)L where L is the total life, then the future life is L - A = 39A.)
Gott’s version of the Traditional Doomsday Argument is relatively simple to articulate: if I consider myself a random sample in my observation of X - e.g. the USA is 231 years old, and let’s assume that I live at a random moment in its history – that is, this moment is a random time within its existence, and I have no further knowledge that would render this moment non-random with respect to its longevity - then there is a 95% chance that the USA will last between 6 and 9009 more years.
The relevance for humanity’s future can now be stated: The naïve Doomsday argument would follow Gott, and reason that if one’s birth occurs at a random time in human history (and given that the origin of Homo sapiens was approximately 100,000 years ago), we should expect there’s a 95% chance that the human species will persist for between 2564 and 3.9 million more years. Or, a 97.5% chance we have at least 2564 years of future. That doesn’t sound so bad.
But the birth rate has dramatically increased in the last few centuries of human history, so from a sheer numbers perspective, this reasoning has a flaw. One better way to think about this argument is in terms of the total number of humans born. My (or your) rank-order among all human births is approximately 70 billion – approximately 70 billion humans have been born before me – so using the Copernican Principle, there’s a 95% chance that between 1.8 billion and 2.73 trillion more humans will be born. If birth rates continue to rise, or even just hold steady (estimated at approximately 130 million a year now), that could mean doom relatively soon – a 95% chance that the last human will be born between 14 and 21,000 years from now!
But this approach is too simple, however. Philosopher Nick Bostrom develops a more sophisticated version of the Doomsday Argument. He first formally clarifies the assumption Gott is making, which Bostrom calls the self-sampling assumption:
(SSA) "Observers should reason as if they were a random sample from the set of all observers in their reference class."
Bostrom’s version of the Doomsday Argument can be explicated using Bayes Theorem, which can be stated as follows:
P(H|D) = [P(D|H)P(H)]/[P(D|H)P(H)+P(D|H')(1-P(H))].
Here’s a way of explaining Bayes theorem - I call it the 10 and 1000 room hotel example. Suppose you arrive at a conference and you’re the first person to check in. The clerk is in control of 1010 rooms reserved for conference attendees – the first 10 rooms (numbered 1-10) in one hotel, and the first 1000 (numbered 1-1000) in a second hotel. As you’re the first person to arrive, he decides to flip a (fair) coin to decide which hotel to put you in, and then has his computer randomly assign you a room in that hotel. He flips the coin, then checks the computer, and hands you a room key – room #7 – but doesn’t mention which hotel you’re supposed to go to! What are the odds that you are in the first hotel?
At first blush, many people answer 50% - after all, he flipped a fair coin to decide which hotel to put you in, so isn’t it 50/50 as to which you got?
No, it isn’t – because you have an additional piece of information – you were randomly assigned room #7. Of course, there are two room #7s, one in each hotel – so how does that help? Well, it helps because (assuming the process is random) you are far more likely to be randomly assigned room #7 in the first hotel, rather than the second. In fact, it’s 100 times more likely!
How’s that? Think of it this way: suppose you repeated this whole process of checking in first at the conference 2000 times. You would then expect, given the coin flip, to stay in each hotel 1000 times. In the 1000-room hotel, you’d then expect to stay in each of its rooms exactly once – including room #7. But the first hotel has only 10 rooms – so if you check into that hotel 1000 times, you’d expect to stay in its room #7 fully 100 times. So if you have a key to room #7, it’s 100-1 odds that you’re in the smaller hotel. (The clerk probably expected you to realize that – or maybe he was just being forgetful!) With only the additional information that you're in room #7, the epistemic odds of being in the smaller hotel have risen from 50% to over 99%.
(Doing the math - Prior: P(H) = 50%, P(D|H) = .1, P(D|H') = .001, so the posterior probability P(H|D) > .99)
So a Bayesian analysis enables one to reason consistently about apparently random events with some prior expectation about their frequency, and to update that reasoning in a consistent manner once more information is learned.
Now to the Bayesian version of the Doomsday Argument – suppose you are optimistic about the future of humanity, so you think the probability of ‘Doom soon’ is very low – say 5%. That subjective antecedent probability is called the ‘prior’ in Bayesian reasoning. But the force of the Bayesian version of the Doomsday Argument is to see that even such optimistic prior assumptions about the future of humanity are overwhelmed by the realization of our place in human history, and it becomes rational to believe (the ‘posterior probability’) that given our evidence, there’s an overwhelming probability that humanity has not much longer to survive. Unless we have some special knowledge about the antecedent likelihood of a long human future, it looks as if we should expect Doom relatively soon.
Or as Bostrom puts it:
"Classic Doomsday - Let a person’s birth rank be her position in the sequence of all observers who will ever have existed.
h1: = “There will have been a total of 200 billion humans.”
h2: = “There will have been a total of 200 trillion humans.”
Pr(h1) = .05, Pr(h2) = .95 are the posterior probabilities of h1 and h2 after taking your low birth rank into account: Your rosy prior probability of 5% of our species ending soon (h1) has mutated into a baleful posterior [probability] of 98%."Bostrom actually argues a more accurate analysis would require a stronger self-sampling assumption:
(SSSA) "Each observer-moment should reason as if it were randomly selected from the class of all observer-moments in its reference class."
The result of the SSSA would be to make the Classic Doomsday argument even more ominous – because not only are birthrates increasing, but human lifespans are getting longer and longer – and so including more and more moments. The result: it would push the rational expectation of Doomsday even closer than a mere counting of the number of births does. Given the SSSA, we might estimate the total number of years ever lived by human beings up to now at 2.75 trillion. That would give a 95% chance that the total number of years left for us all is between 70 billion and 107 trillion. With a current average worldwide longevity of 65 years, that would give us a 95 % rational expectation of between 1.07 billion and 1.65 trillion more births, far lower than the simple SSA forecast. If the birthrate merely remains at 130 million a year, and longevity at an average of 65 years, that means there’s a 95% chance that human births come to an end somewhere between (only) 8 years and 12519 years from now! (And it’s even worse if birthrates continue to rise and/or average lifespans continue to increase). Extinction would presumably follow within at most a century or so afterward – if not simultaneously. Perhaps some science fiction movies aren’t as implausible as they seem.
Bostrom's articles on his website include valuable discussion of most of the objections raised to the Doomsday Arguments above, and counterarguments to those objections. Suffice it to say that some versions of the argument are still held to have force. In fact, I have a novel contribution to the debate, and in it I have some bad news - unless we act quickly, I think our likely future is even shorter than these estimates would imply. My Revised Technological Doomsday Argument will come soon… hopefully, soon enough!
seeing weddings on 7-7-7
As we looked out from our little clifftop over the beach below (beware, those afraid of heights!), there were various little beach inlets, with natural walls where the cliffs went out almost to the water, then receded again to form another beach. The first couple of mini-beaches had the usual - women tanning, kids playing, a black Labradoodle swimming around with a stick in its mouth - but in the third one over, closest to the stairs down to the beach, we saw a bunch of women dressed in vaguely hideous hot pink bridesmaid outfits, and using my immense powers of induction, I surmised there was a wedding going on. When we saw various guys in tuxes with hot pink vests, well... you be the judge.
Upon return home and getting back on what Keith Olbermann likes to call 'the internets', I see that many folks thought 7-7-7 was a mighty lucky day to get married. (Vegas must have had a banner day, and I'm sure the slots were full of customers.) Of course, Tony and Eva were one such couple, as I'm sure even casual NBA fans are aware. I wonder if such weddings will actually beat the odds, as it were? To operationalize this query, let's ask: do people who get married on days they consider particularly propitious get divorced at a lower rate than the average population? Sociologists and anthropologists of the world, a new research question!
In the meantime, I'll stick with other statistical arguments. More on doomsday soon...

The KG sweepstakes
The Laker offer begins with Kwame Brown (expiring contract), Lamar Odom and Bynum, and unless the Lakers can find some way to sweeten it (trading Odom for something more appetizing to Minny, or giving them multiple first round picks?), it doesn't look too plausible.
Dallas apparently is offering Keith Van Horn (re-signed but expiring contract - only 1 year guaranteed), Austin Croshere (another re-signed but expiring contract- only 1 year guaranteed), DeSagana Diop, Josh Howard, and Jason Terry. Dallas would have to pay Croshere and Van Horn some serious coin to make the deal work under the cap, and Minny conceivably wouldn't even bother asking them to actually show up, which would account for their willingness to be a part of the deal. If Minnesota could get Devin Harris instead of Terry, or a high pick like Yi (perhaps by trading Harris to Milwaukee? - it would explain one odd draft-day rumor), things might look better for Dallas. (Minnesota apparently really wanted Al Horford, but that doesn't seem to be plausible anymore.) Dallas wants to keep Stackhouse (and Stack doesn't want to go to Minny), so he won't be part of any deal.
The plausibility of Phoenix's bid apparently depends on their willingness to include Amare, which will become financially easier after his base year compensation penalty goes down in the next few weeks. (Given his guarantee to opt out if traded there, Minny wants Shawn Marion even less than Lamar Odom). I still find it hard to believe the Phoenix owner will countenance adding a $28.75 mil player, especially as it likely makes the luxury tax unavoidable. Would KG waive his $6.75 million trade kicker just to go to Phoenix? I doubt it, especially as it's likely he's going somewhere else where he'd get it.
Chicago is supposedly still a player, though that would require not only Noah, Gordon, Thomas and perhaps Nocioni, but also PJ Brown agreeing to be another re-signed but expiring contract with only 1 year guaranteed - and that one year is with Minnesota. By all accounts Brown isn't keen on that and is already negotiating a contract with Dallas. I suppose 3-way possibilities would exist, but none seem plausible in getting KG to Chicago - and they don't want to be a tax payer either.
The Knicks of course make offers for KG, but without expiring contracts I can't imagine how they could actually land KG - no matter how many unprotected draft choices Isiah offers.
Similarly, Miami is likely in the bidding, as they clearly have a 'win-now' mentality - but while Jason Williams is a nice juicy expiring contract, Udonis Haslem is about all they could offer of any actual value - and that ain't much. If I were them, I'd still offer multiple unprotected draft picks and go for it anyway. A healthy Shaq-Wade-KG triumvirate looks like a near certain Eastern conference champ next season - and their title aspirations are quickly closing otherwise.
The last team clearly in the bidding is Golden State - they can offer Al Harrington, Patrick O'Bryant, Sarunas Jasikevicius (expiring), Adonal Foyle, and some part of the combo of Pietrus, Biedrins, and Monta Ellis. The problem is the lack of expiring contracts - but they have a large trade exception from the JRich deal and could offer to also take on Troy Hudson or Marko Jaric in a separate deal. But they don't want to move Biedrins, and that still leaves Minnesota with a lot of longterm money (esp Foyle and Harrington) coming back.
So, if I had to handicap it right now, I think Dallas is in the lead, with the Lakers second (by desperately concocting some 3-way involving Lamar), and Phoenix and Chicago possibilities only if both the right players are offered AND their owners are more spendthrift than expected. Golden St would move up if they figure out some way to get some expiring contracts. Most likely, I suspect: Kevin McHale is his usual incompetent self, and KG begins the season as a Timberwolf.

Clippers plans, part 2
Elton and Corey to the Lakers, for Andrew Bynum, Vladimir Radmanovic, Brian Cook, and Kwame Brown
For the Clips, building around their core/ long-term contracts of Kaman, Livingston, Tim Thomas, and Cat Mobley, it's a great deal: Kwame's big contract expires next summer and Bynum gives them another young post player, who can either play alongside Kaman, or they can showcase one and trade whichever they prefer. Radman and Cook help space the floor, a problem when Kaman and Brand played together. The team would still be competitive, which is all I think Sterling really requires - so it can get salary cap relief without giving up their future or becoming so horrible that people stop buying tickets.
Meanwhile, Kobe gets a pacifier in Brand plus his pal Maggette, a skilled slasher. The Lakers would still be in the market for a PG, but would also have the option of going huge by pairing Kobe and Corey in the backcourt, which would be tenable with good passers like Luke, Odom and Brand in the frontcourt. And Brand is good enough in the low post to routinely need to be doubleteamed, the key requirement for having the rest of the triangle spacing becoming lethal. The Lakers would become a championship contender, without even giving up Lamar!
I say - make it so.... opinions?
Oden counterfactuals?
But the real shockers are the trades offered by other GMs. Quick reports that a team in their division (Northwest) offered a Hall of Famer and a hyped rookie for the 1st pick - again, simple elimination tells one Minnesota offered KG and Foye for the pick. Even more shocking, Quick claims that another GM from a "Western Conference power" offered a "first-ballot" Hall of Famer for the pick. I don't think the Lakers count as a power, so that could only mean the Spurs, fresh off their championship, offered to trade Tim Duncan! (Unless you think Dirk qualifies as a "first-ballot Hall of Famer" - I do, but I doubt the speaker thought so.)
It turns out Pritchard and his brain trust decided there was only one player in the league for whom they'd trade the pick - LeBron James. I wonder if you folks agree? I do - but then, like Pritchard, I think very highly of Oden.
The news from free agency - Derek and Rashard
Fisher first: I'm not sure of the salary cap implications of this move, but Fisher did NOT say he was retiring (although he's 'thinking about it'), and seems amenable to playing in one of the few cities with specialists in his daughter's rare cancer. The Jazz lose a major rotation player and 'glue guy', but are well positioned to survive the blow, especially if his salary comes off their books, or at least is reduced. Selfishly, I hope Derek continues to play and returns to the Lakers - he is revered in LA by the fans and it is always good to have a player you feel like rooting for on the local team - as opposed to, say, Kobe.
As for Lewis, his move to the Magic kingdom signifies at least these two things: Grant Hill is not returning to Orlando, and neither is Darko Milicic. Grant wouldn't come back to sit the bench (and as blogged before, has several other offers), and they will need to renounce Milicic's cap hold of $6.8 million to make Rashard the offer. The only real question is whether Seattle will try to get Darko or something else back from Orlando by making it into a sign and trade, or whether he leaves for nothing. (Darko should have some suitors, but only a few teams, such as the Hawks, will have the cap room to offer him over the mid-level exception - he may not get quite the payday he was expecting). Rashard should help Orlando spread the floor, but he's a bad defender, indifferent rebounder, and unless Dwight Howard refines his post moves, I don't expect this to make Orlando significantly better.
In Seattle, the obvious plan, from trading Ray Allen and losing Rashard, is to blow it all up and start over, which is why I wouldn't be surprised if they don't simply let Rashard go (and save the cap space, rather than taking on a big contract in return). It's certainly beginning to look like Kevin Durant will be playing on a terrible team his rookie year - but he shouldn't have to fight anyone for shots! Unless new Seattle GM Sam Presti has some tricks up his sleeve, it sure looks like Durant may score more, but win a whole lot less, than Greg Oden for the foreseeable future.

Impeach Cheney?
Now, many in the blogosphere (see this collection of articles) are discussing an article by self-described conservative Bruce Fein that explicitly calls for Cheney's impeachment. A single quote from Fein sums up his argument nicely:
"As Alexander Hamilton advised in the Federalist Papers, an impeachable offense is a political crime against the nation. Cheney's multiple crimes against the Constitution clearly qualify."
Fein's indictment includes the following charges, among many others: Cheney's various methods of disregarding his proper role under the Constitution, including creating line-item vetoes (in the form of signing statements) that the Supreme Court had previously denied; forming military commissions that thwart normal judicial procedure; his contention that military power may be unleashed to kill or capture any American citizen on American soil (if suspected of association or affiliation with al-Qaida - so if Dick Cheney decides (or merely suspects) that you are a terrorist, he believes that the military may shoot you on sight next time you enter an airline terminal); his disregard for constitutional amendments delineating the respective powers of the president and vice-president, and under what circumstances the vice-president should assume presidential powers; and of course, Cheney's latest twist of reality - his farcical assertion that the vice-president is not a member of the executive branch, and is exempt from the Constitutional checks and balances placed upon the executive, and indeed from executive orders regarding the executive branch itself.
So, anyone within shouting distance of a 'strict constructionist' view of Constitutional interpretation would be forced to conclude that Cheney has flagrantly disregarded the document he has sworn to uphold, and hence there are ample grounds for impeachment. Should Congress actually do so? After all, prosecutorial discretion means that even if a crime has been committed, charges do not have to be brought. Some crimes do not deserve prosecution. Cheney's do, however; for his latest transgressions strike at the very heart of what Congress could do to discipline his excesses in the normal way - by exercising congressional oversight of his activities. But he has claimed the extralegal right to keep secret even what he is keeping secret - a meta-secret, if you will - and hence is essentially, by his own admission, acting unchecked by any other branch of government - even the executive! We fought a war to get rid of a tyrant named George III. Let's hope Congress can depose this one peacefully.
