It is one type of cognitive error in estimation of probability to which physicians are known to be prone. The purpose of this study was to determine whether beginning medical stud...

The current paper extends this idea to the situation where participants judge the likelihood of streak continuation. Participants were told about a s...

To test this prediction, subjects in Experiment 1 read a description of a person (e.g., "Linda is 31, bright, ... outspoken") followed by a category. Some s...
