In 1900, only 3% of Americans practiced professions that were deemed "cognitively demanding." Today, 35% of us do, and we have all learned to be flexible in the way that we think about problems. In this fascinating and fast-paced spin through the cognitive history of the 20th century, moral philosopher James Flynn makes the case that changes in the way we think have had surprising (and not always positive) consequences.

I'm gonna kick a hornet's nest. If you Google IQ by country, Africa is at the bottom. He basically explained why that is in the video. So why would we act like IQ is a social construct and tell blacks they are just as smart as whites or Asians. It's just gonna piss them off when they don't get as far cuz they're not gonna assume it's them. They're gonna blame racism or society. We don't do black people any favors by lowering standards for them to get into Harvard only to not have them up to the task and drop out. Now they have all this self doubt and probably student debt. I as a white man have no problem admitting that Jews and Asians are smarter than whites as a whole. It would behoove me MUCH MORE to understand why that is than to fight it.

No where in the quran you'll find that if a girl is raped, her father (or any other relative) is morally bound to kill her. You sir may are spreading false information and Islamophobia; and after listening to this, I cannot take trust your word anymore. Here I thought you were an intellectual.

Has a rather unrealistic view on war at the end. But other than that not a bad talk

1/32 is half of 1/16

12:08 "My father was born in 1885......he did have a sense that black people were inferior", implication of course being that his father was a racist mental defective, and that in fact black and white are perfectly equal in any and all respects. The funny thing about IQ testing is that it has borne out that black people are indeed inferior to white people, and that white people are inferior to asian people. James Flynn is fixed in the concrete mores and attitudes he invented out of thin air on account of social justice, and he will not take reality seriously, never mind the hypothetical.
Tim Fuller
Lots of blather, not much intelligence...
Vinay N.K
This is probably the best ted talk ever.
Harry Stratton
That would make the Donald's grandparents really stupid .

A coherent and inspired voice among the mediocrity of the usual TED talks. Rare event.

Through genetic degradation we have seen a decrease in IQ it is only around I believe 6 % but it has an effect on the overall stats. The degradation is from coming into contact with toxic chemicals .For example PCB's ( Chemical added to material as a fire retardant in the mid 70's which are nowe banned but it's effects are still present in the environment It was banned at the same time as DDT ( pesticide) We have introduced many different toxic chemical into our environment and that is affecting us genetically and our offspring. The results I believe contribute to thee increases in autism, cancers etc from graphs I have seen from the 1960's to present. As for education the big winners are females in the last 30 years and also not mentioned is the failure on basic math and reading skills that many educationalists are aware of. That could be due to the education system or genetics it is uncertain. I enjoyed the talk and I think the point mentioned about thinking out of the square vs thinking in concrete facts and figures is an interesting possibly generational. http://www.cutv.ws/documentary/watch-online/festival/play/7041/jsSendInvitation.php

How language shapes the way we think | Lera Why our IQ levels are higher than our grandparents' 2 months ago   14:13

There are about 7,000 languages spoken around the world -- and they all have different sounds, vocabularies and structures. But do they shape the way we think? Cognitive scientist Lera Boroditsky shares examples of language -- from an Aboriginal community in Australia that uses cardinal directions instead of left and right to the multiple words for blue in Russian -- that suggest the answer is a resounding yes. "The beauty of linguistic diversity is that it reveals to us just how ingenious and how flexible the human mind is," Boroditsky says. "Human minds have invented not one cognitive universe, but 7,000."
