Hackers, please. Let's get real here. Why are Finns so smart? It probably has very little to do with culture, teaching methods, or economics. These can all be limitations (I suspect oppressive teaching hinders Japanese kids), but Finland's secret is not related to any of these. It's related to biology. Finland's secret is brain size.<p>Mother nature doesn't fuck around. If your brain and its activity costs you anywhere from a fifth to a third of your metabolic energy, it's for a reason. This essentially amounts to all the discretionary spending your body has. That brain had better pull its weight, and it does. Skull size correlates with brain weight; brain weight determines surface area; surface area determines processor power.<p>Again, if your brain could be a smaller part of your metabolism, it would be. Mother nature squeezes every calorie for all it's worth. So there is an advantage in having a larger brain. And that advantage translates to being smarter. "Smarter" isn't a particularly mysterious quality either; in biology, it's basically how good you are at deciding what to do with your muscles. In the scheme of things, balance doesn't require much processing power; neither does homeostasis. What is really resource intensive is good old thinking. Writing requires forming markov chains. Memorizing is hard too. Understanding physics is also hard. Thinking--just plain old thinking--is very resource intensive.<p>So, why are Finnish kids so smart? Well, the PISA test doesn't convince me they're that smart. They strike me as being about as smart as white American kids. Thing is, the intelligence of Finns is not averaged out with the intelligence of people of other ethnic groups, who, regrettably, have smaller brains.<p>And before you call me racist, keep this in mind that the argument for different intelligence levels across races is borne out by a data set comprising millions of standardized test-score results, tens of thousands of autopsies, across many different countries, spanning centuries. The correlations have R-values in the .8 and above range. Don't call me racist; call Reality racist.<p><a href="http://en.wikipedia.org/wiki/Brain#Brain_energy_consumption" rel="nofollow">http://en.wikipedia.org/wiki/Brain#Brain_energy_consumption</a>
