An Important Point I Made In Another Thread

[David Sklansky]

This is my response to Lestat on another thread that I thought was important enough to repeat on its own. It concerns a Baye's Theorem type concept that people often get confused about. In this particular case the original subject was the importance of intelligence. But that is not why I am repeating the post here. Even if you think that the argument doesn't apply to intelligence, it does apply to many other important things. I had been meaning to write about this for a while but hadn't gotten around to it until now.

Lestat:

"Of course the forbes list is going to be above average in intelligence, but I'd be willing to bet there are very few among them who do not have someone who's even SMARTER working for them!"

Me:

Since you seem to want to learn, I will go out of my way to explain something to you. And to avoid your biases I will change intelligence to 100 yard dash speed.

I contend that in almost any sport, given no other information, the person with the higher 100 yard dash speed, will be favored to do better at that sport than the slower guy.

Now you point to baseball and point out that while the average speed of professional baseball players is much faster than average, rarely is the fastest player the best player. And that seems to negate my point. Or at least imply that once you get to a certain speed, anything faster hardly helps. Or that somehow the fastest players are weak at other skills DUE TO THEIR FASTNESS. But NONE of that is true.

The reason that the fastest player is almost never the best player stems from two facts.

1. Speed is only one attribute necessarry to succeed in baseball.

2. Super speedsters are MUCH RARER than merely fast players.

This second point is the key. If somehow there was just as many nine flat hundred men in the US as there were 9.8 hundred men (nothing in between and baseball paid more than any other sport) then almost every team's best player would be a 9.0 guy. Because it would be a rarity to find a 9.8 guy whose other skills were sufficiently better than all the 9.0 competion to turn him into the best overall player on the team. But if there is only one 9.0 guy on each team it is likely that among the other 24 guys on the roster, at least one will be able to overcome his speed disadvantage with other skills.

As I said I hope you see that this reasoning helps show the flaws in other similar arguments.

I do not understand something in your post. Your basic premise is this:

[/ QUOTE ]

Yet you qualify this for baseball, thusly:

1. Speed is only one attribute necessarry to succeed in baseball.
2. Super speedsters are MUCH RARER than merely fast players.

While the 2nd point is quite valid, the 1st point seems utterly reduntant within the context you are setting out your argument. It equally, if not more, applies to sports such as volley, diving, weight lifting, etc.

I think you're wrong. First, having the fastest dash time doesn't apply to feilding,hitting,etc.

I think that you're trying to prove a logical point, and your example is flawed.

Shooby.

You're missing his trump card: "all else being equal." He's saying that if you take two players who start out with equal fielding, hitting, catching etc. abilities and talents, but one is faster than the other, then the faster player is more likely to be successful.

Put another way, what he is saying is this: assume you have two people. They are equal in all respects. Now assume one is better than the other in one respect. Which one is more likely to be successful?

Sklansky's style is impetuous, his logic is impregnable, and he's just ferocious. He wants to eat your children.

No, I think he's using 100 dash for athletic ability the same as general intelligence as measured by iq test for intelligence.

"Sklansky's style is impetuous, his logic is impregnable, and he's just ferocious. He wants to eat your children."

Do I have permission to put that quote on the cover of all new editions of my books?

[andyfox]

How about if he changed "fastest dash time" to "best hand-eye coordination"? Would you agree with this?:

I contend that in almost any sport, given no other information, the person with the best hand-eye coordination will be favored to do better at that sport than a person with slower hand-eye coordination.

Now you point to baseball and point out that while the average hand-eye coordination of professional baseball players is much greater than average, rarely is the player with the best hand-eye coordination the best player. And that seems to negate my point. Or at least imply that once you get to a certain speed of hand-eye coordination, anything faster hardly helps. Or that somehow the players with the best hand-eye coordination are weak at other skills DUE TO THEIR HAND-EYE COORDINATION. But NONE of that is true.

The reason that the player with the best hand-eye coordination is almost never the best player stems from two facts.

1. Hand-eye coordination is only one attribute necessary to succeed in baseball.

2. People with Super hand-eye coordination are MUCH RARER than players with merely excellent hand-eye coordination.

This second point is the key. If somehow there were just as many Super hand–eye coordination guys as there were men with merely excellent hand-eye coordination (nothing in between and baseball paid more than any other sport) then almost every team's best player would be a guy with super hand-eye coordination. Because it would be a rarity to find a guy with merely excellent hand-eye coordination whose other skills were sufficiently better than all the super guys to turn him into the best overall player on the team. But if there is only one guy with super hand-eye coordination on each team it is likely that among the other 24 guys on the roster, at least one will be able to overcome his hand-eye speed disadvantage with other skills.

I'm not sure this is the same since hand-eye-coodn isn’t a quantifiable measurement. Or is it? If there is a standard test for measuring h-e-c which is commonly sited by scientist/sports statisticians, then I stand corrected--it’s a perfect example. Barring that, the reason your re-phrasing sounds more convincing is that it is a fundamental *trait* of sports rather than a single quantifiable component, LIKE THE IQ TEST. The David’s contention was (pardon the ratios):

40 yrd.dash:Baseball::IQ TEST:Intellectual Activities
So you CAN be a good baseball player if you are a fat slob (low 40y.d.), it’s just not very likely.
Therefore: You CAN be a good XXXX* if you don’t have a high IQ, it’s just not very likely.
Also: IF you have a VERY high 40, THEN you COULD be a good baseball player.
THEREFORE: IF you have a VERY high IQ, THEN you COULD be a good XXXX.

However I don’t think this analogy expresses the truth of the David’s position. In most of his posts and writing it sounds to me more like he thinks that logic-based reasoning as tested by the IQ test is fundamental to all rational thought, and hence to all activity that employs the mind, including writing jokes! Take some dumb pizza delivery boy from Baltimore and Bill Gates (or whoever) and give them 3 years to write a sitcom pilot. HIIQ would at least be able to logically figure out the rules and tropes of comedy and come up with some passable jokes, while (MOST LIKELY) the pizzaboy wouldn’t, and his sitcom would just be a collection of fart noises.

I think the real If/Then statements look like this:

To be a good XXXX, you MOSTLY MUST have a high IQ.
IF you have a VERY HIGH IQ, you WILL be a good XXXX.

I think you can see that this wouldn’t fit the analogy:

To be a good baseball player, you MOSTLY MUST have a high 40.
IF you have a VERY HIGH 40, you WILL be a good baseball player.

Frankly, I think it is the foundation of the analogy that is incorrect, not the analogy itself. IQ is in fact like a 40yrd dash stat. But figuring stuff out like: “Why am I here? What should I do right now? What is thinking or being or time or whatnot? Is there a God? If there is a god…what is he like?” is not like baseball. When it comes to philosophical reasoning, we’re all idiots.

(Full disclosure:
My IQ is pretty low, so I MOST LIKELY am SCREWED UP somewhere in this post.
My verbal GRE score was 500 points higher than my verbal score. Beat that variance!)


*XXXX=mental activity including but not limited to answering and asking philosophical questions.

[jester710]

I don't know that I would agree that the IQ test is a valid measure of "absolute" intelligence (meaning, I'm not willing to concede that the 125 person is definitely more intelligent, whatever that means, than the 124). My point is that, until we agree on a definition of intelligence or a way to measure it, there will be disagreement over Sklansky's point. I don't know if he meant to or not, but he seems to imply that intelligence is closely related to ability in math or science; would you agree that a person who is more gifted in math and science will be more likely to be successful in ANY endeavor than a person less gifted in those fields?

Sklansky seems to say yes, all other things being equal. I think that if you make all other things equal, then the person with more ability in science and math (Person A) is such an obvious choice that it's not worth talking about. Person A has the same abilities in all other fields as Person B, but excels in one. By virtue of that alone, he would be more likely to succeed.

But if Sklansky truly believes (and I don't know that he does) that science and math skills are closely correlated to intelligence, then you have more of a gray area. For example, Person A is very gifted in science and math. Person B is equally gifted in areas like art and literature. They are equally superior to the other in those fields (meaning A is twice as good at math and B is twice as good at creative writing or whatever). Would anyone say that, given a random endeavor, Person A is more likely to be successful?

[jester710]

While I agree with your premise as stated here, I'm not sure that it stands up when we substitute intelligence back in. I think this is because while there is only one way to measure footspeed, intelligence is too hard to pigeonhole like that. If we were able to agree on an exact definition or indicator of intelligence, then your point would clearly be correct. I think this is basically what Lestat was saying as well.

Although, in rethinking my statement, you may clearly be correct anyway. If your statement is simply that, all other things being equal, the more intelligent person will be more successful, then I suppose it doesn't matter what the definition of intelligence is. Whether it's people skills or math skills or whatever, the "more intelligent" person will be better off simply by being superior in that one category. I think this would be true no matter what the quality in question is (e.g., the better looking one, the one with fresher breath, the better speller, etc.). The slightly superior one has slightly better chances of success. Still, in Lestat's defense, this is purely a theoretical question until we can agree on a definition.
