I think everyone has some bias. It's about owning it, though, and knowing what and what not to say and being open to questioning yourself on whether it's valid.

How does our heretity effect the
choices we had/have today?

Resisting reactionism I think helps deal with most everyday biases. But some are too ingrained. At that point, particularly if they’re ugly or stupid, I try to make mine into a self-deprecating joke. Doesn’t cure it but allows it voice without power.

Honestly I don't think it is possible to exist as a human being without some form of bias
