I invest almost no time and energy making sure I'm not guilty. In seventy-five years of living including a lot of education has made me relatively guilt-free.
Now -- what about YOU?
If you are aware of these biases, rather than feeling guilty, you can become more aware of other possible explanations for your behavior and the behavior of others. Until supporting data is available, it helps to make attributions tentatively.
I hope this helps a little more.
