The definition of confirmation bias as "preference for information that is consistent with a hypothesis rather than information which opposes it" is inaccurately attributed to Peter Wason. In fact, it is Scott Plous himself who presents this definition, after describing some of Wason's work:
"As with the four-card problem, Wason found that subjects tried to confirm the rule (e.g., 8, 10, 12) more often than disconfirm the rule (e.g., 12, 10, 8). This tendency is known as a "confirmation bias." Although the term "confirmation bias" has been used as something of a catch-all phrase (Fischhoff & Beyth-Marom, 1983), it usually refers to a preference for information that is consistent with a hypothesis rather than information which opposes it."
