Key Research/ Experiments
Richard Goranson conducted an experiment in which people were asked to predict how well they would unscramble mismatched letters, then actually try to unscramble them. These people were found to be overconfident in their abilities once they knew the answer. This represented overconfidence, and hindsight bias.
A study of students from the University of Texas recorded about 10,000 30 second bits of each person's life. The study found that people were conversing 28% of the time, and on the computer approximately 9% of the time. This experiment is an example of naturalistic observation.
