Ludwin-Peery, Bramley, Davis, and Gureckis (2019) reported finding evidence of conjunction fallacy errors in an intuitivephysics reasoning task. However, this finding was limited to a single paradigm involving the behavior of only two objects,interacting in a consistent manner, in a highly regular setting. In this project, we provide an important generalizationtest of this result, and examine several new paradigms under which conjunction errors might be observed. We find somecases that produce the expected errors, representing an important generalization of the original finding, as well as someparadigms which do not appear to produce conjunction errors.
