LasersHurt: Could it be that health and nutrition, especially early in life, are hugely important?
van1ty: This is especially remarkable considering IQ tests (or at least not the simon binet) weren't even available 100 years ago.We're so smart, not only do we know how to perfectly measure intelligence (IQ tests -- obviously), but we know how to infer the intelligence of others without even giving them this test!Bulletproof.

Usually every few years when they design anew test they have a bunch of people take it and calibrate it by setting the average raw score of the tests to 100 and curve it with a standard deviation of 10-15 points. You can also take people from that same age group and give them the old test and see how they did. They noticed a steady trend of increases.Of course there is also now evidence that the effect has levelled off in developed countries. I think I read something about it levelling in the mid 90's in the US. Of course apparently scores for numerical reasoning sub-tests have started decreasing.

Saiga410: This is caused by the increased prevalence of single parent households. Kids get confused when mommy and daddy give mixed signals and this retards early learning. Such as when my boy threw a ball in the house and broke mommy's favorite vase. Addda boy nice throw, vs Why you little.If you care about your kids you should get a divorce.
vpb: Because we've gotten better at designing taking IQ tests?
Doc Daneeka: But but....Idiocracy. I've been assured by a million people on the internet that people are getting inexorably dumber over time.
draypresct: Do you have a link? The decreasing trend in math scores doesn't match what I've been able to find.Using NAEP scores (figure 2 of link), there has been a general upward trend in math, while reading ability has either increased or remained relatively constant in the US since 1971. It's difficult to interpret the trend, since I'm not familiar with the units used in NAEP scores (is a 5-point difference a lot?), but it's certainly evidence that there hasn't been an overall decline.Oh, and my guess for "why have IQ scores been increasing" is nutrition/willingness to educate the poor/more resources available (books, computers, etc.) across the economic spectrum*/the concept that education isn't just "stand up in front of the room and recite a memorized poem/fact/whatever"/immigration policies that bias towards highly-qualified people entering the country/etc.etc.etc.
steamingpile: Doc Daneeka: But but....Idiocracy. I've been assured by a million people on the internet that people are getting inexorably dumber over time.They are, I would bet people taking the old IQ tests would not score that high, people have gotten good at hiding how dumb they are.
