All of that can be done, badly. Which is how people do it. See the discourse around any popular drama, people have the skills, they just use them in service of their own pre conceived notions.

It’s bleak, but if you want to persuade a large number of people to think differently, you don’t challenge their worldview, you create new biases that they will then defend in their own.

See: trump’s constant repetition of blatant lies.

The average person has lots of critical thinking.

It’s just not a life hack to truth. You can critical think yourself into any conclusion. The average person uses critical thinking to reinforce their biased instead of challenge them.
