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 fascinated by people like Flynn, possessing a continuity of though enabling them to move seamlessly from one point or concept to the next, without pause, and without having to rely on notes or to stop to formulate the next thought. His is what a highly organized mind looks like.

What a pleasure to listen to someone with enough knowledge, wit and wisdom to speak so clearly, concisely and fluently. And without any props, presentations etc. Beautiful.

What an awesome speaker! I didn't move an inch throughout watching this, and listened with full concentration.

Worth pointing out that this means we should expect the development of high IQs wherever literacy, education, and technically complex professions develop. In other words, IQ differences by country are not innate but a function of material conditions.

His father born in 1885, wow Edit: Dr. Flynn born in 1934 so his father was 49 yo when James was born! And I knew he died 2 years ago, Rest in Peace. He is a very dedicated philosopher, thanks for the work.

Wow! weird concept to think about, I honestly have had debates with my grandparents about morals and using logic and hypotheticals never works. I never stopped to think that they don't think this way.

Thanks Prof James Flynn for your talk! I am from Africa, I can see the benefits of an education, in things like life choices and healthy life styles, even conflict resolution, and the ability to advance in life. Education is definitely something beneficial to humans.
