Confirmation bias (also confirmatory bias, myside bias, or congeniality bias) is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes, for emotionally charged issues, and for deeply entrenched beliefs.

Biased search for information, biased interpretation of this information, and biased memory recall, have been invoked to explain four specific effects:

1. attitude polarization (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence)
2. belief perseverance (when beliefs persist after the evidence for them is shown to be false)
3. the irrational primacy effect (a greater reliance on information encountered early in a series)
4. illusory correlation (when people falsely perceive an association between two events or situations). (Full article...)

• "Don't become a mere recorder of facts, but try to penetrate the mystery of their origin." — Ivan Pavlov

John Broadus Watson (January 9, 1878 – September 25, 1958) was an American psychologist who popularized the scientific theory of behaviorism, establishing it as a psychological school. Watson advanced this change in the psychological discipline through his 1913 address at Columbia University, titled Psychology as the Behaviorist Views It. Through his behaviorist approach, Watson conducted research on animal behavior, child rearing, and advertising, as well as conducting the controversial "Little Albert" experiment and the Kerplunk experiment. He was also the editor of Psychological Review from 1910 to 1915. A Review of General Psychology survey, published in 2002, ranked Watson as the 17th most cited psychologist of the 20th century.
