How to have sane takes on things, in a few easy steps:

1. Consider what you believe.

2. Seek out the best arguments you can find that contradict what you believe, and carefully consider these arguments.

3. If you cannot figure out why these arguments are wrong, and make good logical arguments against them, reduce the credence that you’re right. Perhaps even consider changing your mind.

The end.

Addendum: If you are unaware of good arguments against your deeply held economic, political, or ethical position, this is a very intellectually suspicious state of affairs.
