IQ doesn't say everything about a person's intelligence, but it can say a lot, namely the person's g, or general intelligence. G quantifies the tendency where if a person does well at one cognitive function, he also does well at another. Economists and statisticians who know and work with arbitrary trends and correlations know that IQ correlates a lot with other things, such as a person's (quoting from memory) "overall health, family stability, salary, and so on" I read another thread about "being a jew" which kinda spurred me thinking about IQ and what it means in the real world. After that, I started reading up on Ashkenazi Jews. Really interesting animal. Supposedly there are some populations of Ashkenazi that have AVERAGE IQs of 120, which is insane. There's a 4% chance that any given white person will have an IQ of 140 or more, where for Ashkenazi Jews, it's more like 24%. In other words, a quarter of these particular Jews are near geniuses. But IQ doesn't mean anything, right? It's just a number. Wrong. About half of all world chess championships are won by Jews, despite that fact that they constitute about a quarter of a percent of the world's population. About a third of Nobel prizes go to Jews. The list goes on. I've read a little about why this is. Very fascinating stuff. Here's an article in Wikipedia about Ashkenazi Jews that briefly touches upon their unusual cognitive abilities. CLICK HERE What's interesting about it is that they're the only brand of Jew that exhibit this incredible intelligence. Supposedly other Jews are like regular white people. About 80% of all Jews are Ashkenazi though. Here's a study done at University of Utah that goes into greater detail about their proposed theory of their [Ashkenazi]'s amazing intelligence.

Of course, there are alternative explanations for their high achieving, such as their culture promotes them to acheive more -- which I'm sure it does. Parents put great pressure on their children to achieve more than they had, which, perhaps is a consequence of smart parenting. I have made other observations of the world that suggest that IQ matters a whole lot. But I will refrain for now. What do you think? What does IQ mean in our world? How does it translate into our everyday lives, culture, or whatever you want to mention? Does it matter at all?
