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:
While heuristics are tactics or mental shortcuts to aid in the decision-making process, people are also affected by a number of biases and fallacies. Behavioral economics identifies a number of these biases that negatively affect decision making such as: Present bias. Present bias reflects the human tendency to want rewards sooner. It describes ...
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.
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.
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]
The availability heuristic, also known as availability bias, is a mental shortcut that relies on immediate examples that come to a given person's mind when evaluating a specific topic, concept, method, or decision.
It is one of the earliest economic theories that explicitly acknowledge the notion of cognitive bias, though the model itself accounts for only a few, including loss aversion, anchoring and adjustment bias, endowment effect, and perhaps others. No mention is made in formal prospect theory of cognitive bias mitigation, and there is no evidence ...
