Pseudocontingencies: an integrative account of an intriguing cognitive illusion.
The term pseudocontingency (PC) denotes the logically unwarranted inference of a contingency between 2 variables X and Y from information other than pairs of xi, yi observations, namely, the variables' univariate base rates as assessed in 1 or more ecological contexts. The authors summarize recent experimental evidence showing that PCs can play a pivotal role in many areas of judgment and decision making. They argue that the exploitation of the informational value of base rates underlying PCs offers an alternative perspective on many phenomena in the realm of adaptive cognition that have been studied in isolation so far. Although PCs can lead to serious biases under some conditions, they afford an efficient strategy for inductive inference making in probabilistic environments that render base-rate information, rather than genuine covariation information, readily available.
