The best ideas and theories are those developed by defeating the counter-hypothesis.
Surprises, insights, and great discoveries come from challenging prevailing wisdom, ideas, and perspectives.
Learning requires asking questions. Asking hard questions requires examining what you believe and why it might be wrong. Humble yourself and re-examine your ideas; it will make you a better decision maker.
Asking many people with the same perspective only amplifies the errors that they have and you have.
Don’t seek why you are right, but rather examine how you might be wrong.
