John believes that there are a lot of differences between men and women on a variety of different dimensions. He believes this because when he thinks about books that have been written on men and women, he can recall only books that say men and women are different (e.g., Men Are from Mars, Women Are from Venus) and cannot recall any that say men and women are the same. His reliance on what comes to mind is an example of which type of reasoning?
a. The availability heuristic
c. Confirmatory hypothesis testing
b. Cherry-picking of evidence
d. Overconfidence

The availability heuristic is a term that is used in decision making. It occurs unconsciously. According to this term what comes in your mind is most important. In this term, the psychologist thinks that things that come in our minds frequently are more common and most important for us. These terms reflect the world image through these terms. It is a shortcut to make the decision. But this the common shortcut that is used to make the decision quickly called availability heuristics.

John believes that there is a lot of difference between men and women because of the availability of books written on men's and women's differences. He can not recall does anyone say that men and women are the same. This is an example of availability heuristics.
