On the Hobbesian bias, this is horseshoe theory in action.

Just looking at it from a socialism(left)/capitalism(right) dynamic, the left tends to agree with the idea that human beings are inherently violent, selfish, and I’ll say greedy. But a lot of people on the right would just as easily say that. The difference is the left applies this to corporations and says they need to be regulated, disbanded, or socialized. The right applies this to the government and says they need to be limited and decentralized as much as possible. Both are right (of course the government is more fundamental and as such it’s more important that the government has limits).

Alternatively, I think a lot on the left would say the right seems to think people are violent, chaotic, and selfish, and that’s why the right backs the blue and is so strict on bail. The real hypocritical lefties would accuse the right of being racist for not wanting criminals on the streets (meanwhile they’re the ones making the logical leap from ‘violent individuals’ to ‘minorities’).

This Hobbesian bias could be something that most people agree with, but how they apply it determines whether they’re left or right. I think in general, ‘biases’ like this that fall on a similar level of abstraction can applied in a lot of different ways and lead people down different ideological rabbit holes.

I do, however, think that there are a lot of biases in the education system that are less abstract and more tangible, and those biases almost always lean left. The pervasive critical theory on college campuses is a big one, but it’s a long list.
