What is Are Absolute Frequencies, Relative Frequencies, or Both Effective in Reducing Cognitive Biases? about?

Biases in probabilistic reasoning are a}ected by alterations in the presentation of judgment tasks[ In our experiments\ students made likelihood judgments that an event was produced by various causes[ These judgments were made in terms of probability\ relative frequency or absolute frequency on a full or a pruned list of causes[ When they had little personal experience of the event "causes of death#\ the pruning bias was smaller with relative frequencies than with absolute frequencies or probabilities[ When they had more personal experience of the event "missing a lecture#\ the bias was less with both types of frequency than with probability but still lowest with relative frequency[ We suggest that likelihood information is usually stored as relative frequencies when it has been obtained from public sources but that it is based on event counts when it is derived from personal experience[ Copyright Þ 1999 John Wiley + Sons\ Ltd[ KEY WORDS sub!additivity^pruning bias^de!biasing Likelihood can be expressed using a probability format "e[g[ 9[91#\ a relative frequency format "e[g[ 19 in every 0999\ one in 09\ 04)#\ or an absolute frequency format "e[g[ 0921 British schoolgirls 0 #[ This
