The three way filters to keep bullshit away:
1. As Munger said: “Show me the incentive and I’ll show you the outcome.” Be wary of views coming from people who are not free to speak their minds on the topic at hand, because of their existing incentives.
2. Favour views from those who get paid for being right, discount views from those who get paid for sounding right.
3. The balance of power is being overturned by information technology. Favour people who deeply understand it and work it into their world view.
