(Humans Invent)   If you score the people a century ago against modern norms, they would have an average IQ of 70. If you score us against their norms, we would have an average IQ of 130...so what's making us more intelligent?   (humansinvent.com) divider line 126

I am calling BS. I have seen on the internet schoolhouse exams for 6th graders from the golden age of America individualism that show people were much smarter back then. This was of course due to the non-liberal education that has transformed America in to a bunch of commies or something.

Our brain process a lot more information, just from a single source. 

A certain color, a certain tune,  and/or a certain font can evoke a specific brand...

Compare the first trailer of Die Hard with Die Hard 5...

The original Die Hard needed a narrator to walk us through, giving us bullet points of what the movie is about. 

The latest Die Hard trailer only needs to have Ode to Joy playing while a door opens to quickly evoke the scene with Hans Gruber as they finally open the safe in the original movie, instantly telling us "THIS IS A DIE HARD MOVIE"

I'm curious how much of the effect is due to better nutrition, improved public health measures, prenatal care, and better medical technology.

For example, the authors of this paper (  http://www.nber.org/papers/w19233 ) posit that iodization of salt accounts for a big chunk of the IQ increase.  The effects are large enough to account for one decade of the Flynn effect.

Not as much as you'd think.

More likely IQ tests are just a fairly bad measure of real intelligence. That's why there's strong cultural biases.

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!

The original observation came from looking at IQ tests since they did become available in the 1930's. 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.

Race mixing. As humans become "mongrelized", we will get smarter and healthier, just like dogs do - diversity is the key to genetic success.
 
2013-10-11 09:35:56 AM
Our IQ's have gone up over time due to a variety of reasons, some of which have been mentioned.

Better nutrition, less exposure to heavy metals (lead from leaded gasoline lead to generations of people with higher than average rates of mental disorders, especially violent ones, and lower IQ), early childhood education that focuses rather heavily on problem solving abilities which are the foundation of human intellect, and also unfortunately 'teaching to the test'.

Overall, a modern child of the same age as someone from 100 years ago would on average be MUCH better at abstract problem solving thanks to these causes, though im guesstimating that a good 60% of that is due to mere early childhood education.

seriously, intelligence is only loosely linked to genetics. the major determining factor of a persons later life intelligence is the level of early childhood education, which just so happens to be much higher in middle and upper class families than the very poor...

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.

If I had to guess, I'd pick the selective effects of civilization.

Nature doesn't provide strong mental challenges the same way that other people do.
Despite the "stupid breeds more" theory, its the children who evolve better skills (memory, language skills, technical ability, overall intelligence) that grow up to earn more. High earners avoid more diseases, have more options in partners, and have children who survive more often.

Intelligence is sexy inside of our social and economic structure.

It's not mentioned, so I'm going to assume if you score us against modern norms, we would have an average IQ of 65.

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.
 
2013-10-11 09:49:31 AM
Wouldn't this be an apples-and-oranges thing, thus making the question sort of meaningless? I wasn't alive back then and I'm neither a historian nor a psychometrician, but it seems pretty obvious that being a success in 1913 and 2013 require vastly different skill sets, knowledge bases, credentials, etc.
 
2013-10-11 09:49:42 AM
Well, so far, this thread isn't proven that whatsoever...

But to answer the question, I'd go with access to schooling, more stimulus since birth, educational shows, toys that aren't sticks, better nutrition, and parents that gave a damn (at least some did) instead of being out there trying to survive, etc.

But as the next generation can't do crap without a computer/phone/tablet and their idiot parents letting them sit on their arses and do nothing than play the shiny App on their devices so to shut them up, this should slowly return to lower scores.

But the thing about IQs, it's technically hard to really judge... I mean if most in here are about 100 (average rate, and not the genius most think they are) but one hits 180, it does mess with the curve.

It was based solely on the Numerical Reasoning portion of the IQ tests, so it would likely overlap but not be identical to NAEP scores I would assume. And my bad, the study that showed a decrease in numerical reasoning was in Norwegians not the United states. (http://www.sciencedirect.com/science/article/pii/S0160289604000522  )

If you look at even the wiki entry for the Flynn effect a lot of your ideas are all considered part of it. People go to school for much longer on average now than ever before, we eat better, and more adults are in cognitively demanding jobs (cognitively demanding compared to stock manual labour that is).

Except that isn't true, as evidenced by you know, actual research and not just pulling something out of your ass. There are still a lot of dumb people, but then again what many of us would consider "dumb" doesn't necessarily translate in to a low IQ. There's a difference between stupidity and ignorance after all.
