I noticed that introversion and autism share a lot of features.
1. Sensitivity.
I read about a famous experiment by Kagan. They tried to estimate the reactivity of children to certain stimuli (by measuring changes in heart rate, for example). They then categorized them into two groups: the highly-reactive group, and the other group of those who responded less intensely. Then, in a few years, they assessed their personality types, and, surprisingly, the ones who responded more intensely were more likely to become introverts, and the other group, who responded less intensely, were mostly extroverts when they grew up.
There is another more recent experiment that used fMRI (functional Magnetic Resonance Imaging—to measure the brain activity in response to something). That, too, concluded that introverts are more likely to have higher reactivity to stimuli. Their brains show more activity than those of extroverts. Yet, introverts are known to be the ones who speak quietly and, on the outside, they don't seem to respond more intensely. Just like autistic people.
2. Social Interaction
I don't think we actually need a scientific evidence to that—introverts are more likely to be socially awkward, too. And they prefer solitude.
3. Empathy
Introverts, too, are more likely to be sensitive and sympathetic than extroverts.
Could autism be just an "augmented" version of introversion?
