AbstractMany theories of reasoning and many experiments presuppose that human ability is stable over time, and so people usually draw the same conclusion from the same premises. The assumption has hitherto had little or no empirical investigation. We therefore analyzed a study in which 20 participants drew their own conclusions to the 64 sorts of syllogisms on two occasions separated by roughly a week. We report the nature of the changes in the participants’ conclusions including their spontaneous improvement in logical accuracy, and use a model-based program, mReasoner, to explain the results.
