Here we focus primarily on Bayes factors and minimum description …Share button law of parsimony the principle that the simplest explanation of an event or observation is the preferred explanation. Simplicity is understood in various ways, including the requirement that an explanation should (a) make the smallest number of unsupported assumptions, (b) postulate the existence of the fewest entities, and (c) invoke the fewest unobservable constructs.The two views that parsimony is “minimizing evolutionary changes” or “minimizing ad hoc explanations” is part of a larger tension between pattern and process.

- a site or pattern is “parsimony-informative” if it follows what I call the 2-2-2-rule: To be parsimony-informative, it has to have at least 2 different (unambiguous) characters, and of those at least 2 have to occur at least twice. The reason is that parsimony tries to group sequences together that share the same characters.Study with Quizlet and memorize flashcards containing terms like 1.

The principle of parsimony indicates that when 2 theories account for the same facts, the one that is briefer, makes fewer assumptions and references to unobservables, and has the greater generality is to be preferred. It is argued that psychologists often violate this principle, particularly when attributing complex behavior to cognitive processes.
