There are many mental traps that you can fall into when making decisions. Knowing what they are can help reduce, but not eliminate, the chance of making errors in judgement. It is better to focus on what not to do (via negativa), ie: what factors contribute to failure/bad decisions and try to avoid those. It is unclear what consistently causes success, but we have a good sense of what doesn’t cause success. Following this line of thinking is common among many successful people – they understand their limitations (or circle of competence), and do their best to act within them.
The Art of Thinking Clearly revisited some biases I was already aware of from reading about similar topics, and introduced me to some interesting ones such as the Feature-Positive effect: how it’s much harder to notice the absence of something than the presence of something.
As a result I made a simple list, possibly to be used as a checklist, of the biases listed in the book. I plan to revisit it often, especially when making major decisions or examining specific opinions I hold to see if I’m falling into any traps.
Note: this is just a direct copy/paste from the Table of Contents, so some things may not be clear if you haven’t read the book.
