Why Smart People Defense Bad Ideas?

The document discusses why smart people sometimes defend bad ideas. It provides several reasons why this occurs, including that proficiency in logic and argument can be used to defend wrong positions, a desire among smart people to always be right even if based on delusion, and thinking within a homogeneous group that limits diversity of ideas. It recommends seeking diverse perspectives and experiences to avoid narrow thinking and addressing problems at the right level rather than getting distracted by less important issues.
