I'm curious to query the HN crowd: How do we mesh this learned helplessness on subjects for which there are no definitive studies for? (eg. is the purpose of a human life to produce more humans? How does one formally prove that, and how does one prove those proofs are valid, and the organizations that prove the proofs are valid are also valid?)
(This is the opposite of the "instant expert syndrome" to which many people seem susceptible, where they are certain they know which side to take about whatever was recently in the news.)
In real life, you probably do have commitments and decisions to make.
