On the Scrabble and IQ debate, or why mastering Scrabble doesn’t require genius

My answer to the Scrabble-IQ debate which keeps coming up on the Unz Review, from a comment I wrote on there:

The entire debate may be about crystallized versus fluid intelligence.

Scrabble requires that one be intelligent enough to be able to “crystallize” the patterns for solving each situation, so that a person can do it without having to think about it the next time they run into the same situation, but no more intelligent than that.

Winning games like chess and Scrabble requires some fluid intelligence (IQ), and massive amounts of crystallized intelligence (stored solutions), which is why they need so much training.

If you are familiar with computing, it is easy to understand what this means. A lower-IQ person can simulate high IQ in a game like Scrabble using this function:

solve(game_context) {
  if(cached_answer_exists(game_context)) {
    return get_cached_answer(game_context); // extremely fast, even for a low IQ person
  else {
    return compute_answer(game_context); // slow, even for a very high IQ person

So a game like Scrabble has a very high “caching advantage”, a person who spends immense amounts of time with it will have thousands, maybe millions, of cached answers in their heads, that enable them to nearly instantaneously find the solution for a new game context, because there is no computation involved, the solution is cached in their brains.

A lower-IQ Scrabble “genius”, however, will be incapable of mastering a topic of study they have never studied before (such as economics), so that they can quickly come up with original and interesting solutions and ideas within the field, because their genius is about being good at caching answers. Their genius has nothing to do with fluid intelligence, the type of intelligence needed to handle massive data, operate on it and synthesize new things from it. Your millions of cached Scrabble solutions are just that, millions of cached Scrabble solutions. A Scrabble genius is like a computer that has tons of Scrabble solutions and is very good at winning Scrabble games, but that cannot do much of anything else. The computer is not an AI genius, it simply has a hard drive that is filled with canned solutions.

My hypothesis, therefore is this: A race or nationality’s ability to master Scrabble does not predict its intellectual, scientific or technological achievements, because Scrabble does not require very high IQ, while the rest of these things do.

In fact, I would hazard a guess that very few really-high-IQ people (135+) bother to play games like Scrabble, because they would rather do something open-ended, rather than something entirely unproductive, with their time. Almost everyone I have met who was dedicated to chess and similar closed-ended games has not been an intellectual genius who could say something intelligent and interesting about geopolitics, for example.

I do not enjoy watching sports, and no really-high-IQ person I know enjoys them either, because it is closed-ended. There is only so much that can happen. We soon get a feel for the game and get bored with it. We would rather play a complex computer simulation game where we can manage the affairs of an empire, even though this too ultimately gets boring so that we start to read hundreds of books on economics and history like maniacs.

Another hypothesis is this: A Scrabble genius will be very bad at games with a low caching advantage. Thus a race or nationality that is good at Scrabble will perform worse at Go than a higher IQ nation, because Go has a lower caching advantage (it requires more fluid intelligence, i.e. IQ, since the situations that arise in the game are too diverse to cache, there will of course still be some caching advantage, therefore we must find a game that has a very low caching advantage, such as…Raven’s Progressive Matrices1).

A theory for why pupil size is associated with intelligence

People of higher intelligence have wider pupils than people of lower intelligence. A possible reason for this is that a wider pupil allows more photons to enter the retina. A person of higher cognitive capacity will be able to make good use of these photons, as they have the hardware to analyze the added photons, meaning the increase in the amount of photons entering the retina provides a selective advantage for these people.

In other words, when high intelligence is paired with wider pupils, human vision becomes more powerful, as there is more visual data received, and there is the power to process these data. By taking in more photons, these people are able to have better distant vision (as their pupils offer a wider surface area for distant photos to be captured) and better peripheral vision, giving them an advantage in hunting and warfare.

The theory, therefore, is that higher intelligence and wider pupils together enable humans to have higher visual fidelity compared to other humans. Add this to the much faster reaction times of a high IQ person and you have a hunter-killer that is far superior to others.

This means that as if high IQ privilege wasn’t bad enough, high IQ people also have the privilege of seeing the world better. I am sure a clever cultural Marxist can be found to support a law to force high IQ people to wear glasses that filter out the added photons, so that equality can be achieved.
