It helps to remember that the mind is not a truth machine, but a survival machine.
I recommend learning some psychology. The more you know about how the mind works, the easier it is to understand and spot logical fallacies, both in yourself and others.
Edit: also, you should practice those critical thinking skills instead of just keeping them in theory. You could apply them to past situations, for example.
It wouldn’t solve everything, but at least there wouldn’t be room for chronic reification, useless charismatic narcissists, Cartesian dualism, etc to become big issues like they are in our world.
My point isn’t that autistic people have a single, utopian personality, but that we’re generally less susceptible to certain social/psychological phenomena that tend to make societies shittier.
