You're Dumber Than Your Grandparents (Science Proved It)

For 50 years, we got smarter. Now, for the first time in history, IQ scores are crashing. This is why:

Do you think you're smarter than your grandparents? Most people do. But science says otherwise.

For 50 years, every generation scored higher on IQ tests than the one before. Researchers called it the Flynn Effect, and it was one of the most consistent findings in cognitive science. Then around 1995, the trend reversed. IQ scores started dropping.

A massive study tracking over 1 million people across 8 countries confirmed it — human intelligence is declining.

And it's not genetics.

Researchers proved that by comparing brothers from the same family. Same parents, same DNA, same household. The younger brothers scored lower.

So what changed? Three things. One is rewiring your attention span right now. Another was quietly removed from your food decades ago. And the third is something no one saw coming.

In this video, we break down the Reverse Flynn Effect, what's causing the decline in cognitive ability, and why the skills dropping fastest in humans are the exact same ones AI is getting better at.

The good news is this: the research shows it's reversible.

The question is whether we actually do something about it.
