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. In other words, the availability bias is a mental shortcut that relies on us using immediate examples that come to mind to make our current judgements or decisions, as opposed to using logic. The availability heuristic includes or involves the following ->
Survivorship bias
Anthropocentric thinking
Salience bias
Selection bias
Negativity biais
Concentrating on the people or things that "survived" some process and inadvertently overlooking those that did not because of their lack of visibility.
The tendency to use human analogies as a basis for reasoning about other, less familiar, biological phenomena.
The tendency to focus on items that are more prominent or emotionally striking and ignore those that are unremarkable, even though this difference is often irrelevant by objective standards.
Happens when the members of a statistical sample are not chosen completely at random, which leads to the sample not being representative of the population.
We tend to make our decisions based our past negative experiences.
