There's actually science behind it.

A brain scan can reveal a person's political leaning with like 80% accuracy, and I can't stress enough how crazy that number is, the remaining 20% usually just aren't political or in the middle.

It's done by looking at the size/activity of the amygdala and the prefrontal cortex.

A conservative will have more amygdala activity, which is our flight or fight response.

A progressive will have a larger preferential cortex, the part that gives us logic and empathy.

It's always important to mention that this isn't permanent, our brains are like muscles, use certain parts and they get more active and even physically larger (but obviously on a small scale).

We know that because there's been studies on London taxi drivers. Before training their brains are normal. But since they have to memorize every street in London, by the time they're certified there's a noticable difference in the part of the brain that handles navigation.

So it's not like theyre a lost cause.

And why republican leaders are so hell vent on removing "liberal arts" from schools. The people leading aren't idiots, they're trying to make more conservatives
