How do you measure intelligence?  IQ test?  Technological advancement?  Reaction time?

If you use these universal standards as measurements for intelligence, you would find that humans are advancing rapidly with every generation.  But are we really smarter than our grandparents - or do we just think differently?  

Jams Flynn, an intelligence researcher and emeritus professor of the University of Otago in New Zealand has defined what he calls the "Flynn effect" -- the fact that each generation scores higher on an IQ test than the generation before it.   Flynn has written extensively about the connection between equality, IQ gains, democracy and human rights.  And in this fascinating TedEx talk, he walks us through history and suggests that those higher IQ scores are actually due to changes in the way we think -- changes that have had surprising (and not always positive) consequences.

So if you're ready for some "deep thoughts" on thinking, checking out this thought-provoking talk (and don't forget to let us know what you think:)
