Annie Duke: don't judge an idea based on the messenger

Acceptance or rejection of an idea must not ‘depend on the personal or social attributes of their protagonist’ … [D]on’t disparage or ignore an idea just because you don’t like who or where it came from.  When we have a negative opinion about the person delivering the message, we close our minds to what they are saying and miss a lot of learning opportunities because of it.  Likewise, when we have a positive opinion of the messenger, we tend to accept the message without much vetting.  Both are bad.
