Neglect of Probability

Neglect of Probability is a cognitive bias where individuals completely disregard the statistical likelihood of an event when making decisions, especially when the outcome is emotionally charged. Coined by Cass Sunstein and explored by Rottenstreich and Hsee in 2001, this mental model explains why we fear rare shark attacks while ignoring the common risk of driving, and why we spend billions on lottery tickets despite the near-zero odds. Understanding Neglect of Probability allows decision-makers to replace "vividness" with "expected value," ensuring resources are allocated based on actual risk rather than emotional intensity.

Optimism Bias

Optimism Bias is a cognitive phenomenon where individuals overestimate the likelihood of positive events and underestimate the likelihood of negative events happening to them. Formally identified by Neil Weinstein in 1980 and expanded by neuroscientist Tali Sharot, this mental model explains why we under-save for retirement, smoke despite health warnings, and launch doomed business ventures. Mastering the Optimism Bias allows for "Defensive Pessimism" and more accurate risk assessment without sacrificing the motivation and resilience that a healthy level of optimism provides.
