In 1967, a probability survey was published in Psychonomic Science. The study asked people to place a percentage figure next to a series of adjectives describing the liklihood of an event occuring, for example "Highly Probable". In 2005 and 2006 I repeated this experiment on a small scale with friends, family, and some school students. The results of this experiment are shown below. If you would like to submit your probability estimates to be included in the study please e-mail me.

The detailed results and statistical summary from the experiment are shown below.
