Just finished "Thinking in Bets" by Annie Duke.
It explains some of the cognitive biases we have when making decisions and proposes another way to thinking about decision making. instead of "right" and "wrong" decisions, it shares the concept of thinking of decision making as
1. examining our set of beliefs (facts, assumptions, unknowns)
2. make a bet (ie informed decision based on being the most accurate facts we can gather)
3. planning for possible outcomes by painting out the scenarios and the probability of each scenario.
4. learning from the outcome and updating our beliefs
the key points seems to be that informed decision making leads to better long term outcomes, the best bets may not turn out successful which does not mean it was the wrong decision to have made based on what was known, people who carefully examine the scenarios and therefore learn from the outcomes and thinking process will fare better in the long run.
