The Internet has revolutionized the world. We have unprecedented access to nearly unlimited amounts of information. While this is indisputable, are we really dumber than ever? The answer isn't that simple.

IQ test scores have increased an average of 3 points per decade during the 20th century.

If measured on an unadjusted scale, the current generation would have IQs more than 20 points above those of their grandparents.

However, IQ doesn't tell the full story. Stanford geneticist Gerald Crabtree argues that people now are dumber than ever. Crabtree controversially argues that human intelligence peaked before the rise of the hunter-gatherer:

"A hunter-gatherer who did not correctly conceive a solution to providing food or shelter probably died, along with his or her progeny, whereas a modern Wall Street executive that made a similar conceptual mistake would receive a substantial bonus and be a more attractive mate"

So while there isn't a consensus on if we're dumber today, we want to present this debate in a relatable way - Let's take a look at standard American curricula for the past century. Think you can pass your grandma's test?
