The availability heuristic (also known as the availability bias) is the tendency to overestimate the likelihood of events with greater "availability" in memory, which can be influenced by how recent the memories are or how unusual or emotionally charged they may be. [20] The availability heuristic includes or involves the following:
A continually evolving list of cognitive biases has been identified over the last six decades of research on human judgment and decision-making in cognitive science, social psychology, and behavioral economics. The study of cognitive biases has practical implications for areas including clinical judgment, entrepreneurship, finance, and management.
Behavioral economics is the study of the psychological (e.g. cognitive, behavioral, affective, social) factors involved in the decisions of individuals or institutions, and how these decisions deviate from those implied by traditional economic theory. [1] [2] Behavioral economics is primarily concerned with the bounds of rationality of economic ...

[102] The present securities regulation regime largely assumes that all investors act as perfectly rational persons.

Scarcity heuristic: A cognitive bias where people assign greater value to items or events that are perceived to be in limited supply. This mental shortcut assumes that limited availability signals higher worth, leading individuals to overvalue things that are harder to obtain as exemplified in behavioral economics. [54]
Kahneman became known as the "grandfather of behavioral economics." [2] [3] [4] With Amos Tversky and others, Kahneman established a cognitive basis for common human errors that arise from heuristics and biases, and developed prospect theory. In 2011, Kahneman was named by Foreign Policy magazine in its list of top global thinkers. [5]
Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality. Although it may seem like such misperceptions would be aberrations, biases can help humans find commonalities and shortcuts to assist in the navigation of common situations in life.
