Failure of the Experiential System: The Case of Smoking
The experiential system's focus on immediate affect and sensitivity to small changes leads to poor long-term decisions, as illustrated by smoking addiction where young smokers underestimate future cravings and risks.

False Consensus Effect
The false consensus effect is a cognitive bias where people overestimate how much others share their own beliefs, attitudes, and behaviors. In social situations, this leads to assuming that one's own reactions are universal, as illustrated by the author's surprise that many people feel less awkward when awkwardness is acknowledged.

False Context
False context presents real material, such as a video or quotation, with a misleading account of what it shows. A shortened clip and a false caption can make ordinary events appear to support a claim that the full context contradicts.

Favorite-Longshot Bias
The favorite-longshot bias occurs when betting-implied win probabilities are too low for favorites and too high for longshots. Risk-seeking and attempts to recover losses are proposed explanations. The passage also describes how differing base rates affected the calibration of sports commentators.

Features of Hypotheses: Evaluative Quality and Self-Relevance
This concept describes two key features of hypotheses—evaluative quality (positive vs. negative framing) and self-relevance (hypotheses about oneself vs. others)—that systematically influence how people recruit evidence and judge support, often leading to motivated reasoning and biased conclusions.

Feeling Objective Doesn’t Make You a Scout
Feeling calm and rational does not guarantee objectivity; it can actually reinforce bias by making you trust your intuitions uncritically. The illusion of objectivity leads to motivated reasoning, as seen in Lawrence Krauss's defense of Jeffrey Epstein based on personal trust rather than evidence.

Framing Effect
The framing effect is a cognitive bias where people react differently to a choice depending on whether it is presented as a loss or a gain, even when the options are mathematically equivalent. For instance, '72% survival rate' feels more reassuring than '28% mortality rate'.

Generalization to Aspects of Accuracy Other Than Overconfidence

Getting annoyed when an ideology is criticized
When someone criticizes a group or belief system we identify with, we often feel a defensive reaction, even if the criticism is mild or true. This cognitive bias stems from the involvement of our identity and can prevent rational evaluation of the critique.

Goals Are Reference Points
Loss aversion shows we are more driven to avoid losses than achieve gains, and goals act as reference points where failing to meet a goal is a loss and exceeding it is a gain. This asymmetry leads to behaviors like working harder to avoid a bogey in golf than to achieve a birdie.

Golden Mediocrity
The concept of 'Golden Mediocrity' refers to the historical ideal of the average or mean, popularized by statistician Adolphe Quételet, who defined a 'normal man' (l'homme moyen) through statistical averages and treated deviations as abnormal.
