The writer of the book 'How to Fail at Almost Everything & Still Big' Adams had a lot of middle and middling experience in the business world and credits himself with an advanced bullshit detector. “Realistically, most people have poor filters for sorting truth from fiction , and there’s no objective way to know if you’re particularly good at it or not,” writes Adams. How then do we do it? Adams has six filters for truth. The more filters something can pass through, the more true it probably is. The Six Filters for Truth are as follows: 1. Personal experience (Human perceptions are iffy.) 2. Experience of people you know (Even more unreliable.) 3. Experts (They work for money, not truth.) 4. Scientific studies (Correlation is not causation.) 5. Common sense (A good way to be mistaken with complete confidence.) 6. Pattern recognition (Patterns, coincidence, and personal bias look alike.) Adams admits that each on their own has limited filtering ability, but combining more than one gets better refinement. (Source: mikevardy.com/blog)
