six filters for truth personal experience
- (Human perceptions are iffy.)
- Experience of people you know (Even more unreliable.)
- Experts (They work for money, not truth.)
- Scientific studies (Correlation is not causation.) Scientists creep up on the truth by performing controlled experiments and attempting to observe consistent results.
- Common sense (A good way to be mistaken with complete confidence.)
- Pattern recognition (Patterns, coincidence, and personal bias look alike.)
