Does anyone else feel like 90% of the population is stupid?
To clarify here, I don't feel like I'm significantly smarter than most people, but I feel like people have a hard time doing any sort of thinking about stuff. Especially when it comes to verifying "facts."
I mean if it is a bell curve, even an average person is smarter than half the world. There's a selection bias on social media because those heated and ignorant threads get memed and shared either by people who believe the nonsense or by outrage.
Most tests of intelligence lands close to a bell curve. With how many different factors that can influence intelligence it seems quite likely (the average of many different distributions each with a peak in the center is likely to look like a bell curve)
More precisely: If you repeatedly draw values from a probability distribution and sum them up, the sum tends towards a Gaussian (central limit theorem).
