Dealing with intellectual insecurity

There are two approaches:

• "Leave it to the experts." While it is true that the most informed speak the clearest, it is also true that fields of expertise can develop closed intellectual cultures where certain assumptions get ingrained.  The best answers come from open and deliberate processes.
• Try to be honest but humble. Do your best, and be open to changing your mind if some people who know more than you disagree with you.
