Biases and heuristics

Biases and heuristics are formed through slow analytical thought from a lifetime of experience, both personally and clinically.   Biases (and heuristics) run in my fast intuitive system and help me make a lot of efficient decisions every day.   When they are not working for me, I move back into the slow analytical system which is more effective, but less efficient.

I have a bias towards the truth.

Most people do.  Most believe others are telling the truth more often than they actually are.

How often do I question that bias when listening to others?  How often do I question that bias when I am listening to myself?
