A systematic account of probabilistic fallacies in legal fact-finding

Evidence scholars have observed probabilistic fallacies in legal fact-finding and given them names since the 1980s (for example 'Prosecutor's Fallacy' and 'Defense Attorney's Fallacy'). This has produced a rather un-organised list of over a dozen different probabilistic fallacies. In this article, the author proposes a systematic account where the observed probabilistic fallacies are organised in categories. Hierarchical relations between probabilistic fallacies are highlighted, and some fallacies are re-named to reflect the category they belong to and their relation to other fallacies in that category. All fallacies are precisely defined and illustrated with examples from real cases where they are committed by fact-finders. The result is a list of 12 probabilistic fallacies organised into 7 categories.
