The rationalizability concept was introduced in (Bernheim 84) and (Pearson 84) to assess what can be inferred by rational players in a non-cooperative game in presence of common knowledge. However, this notion can be defined in a number ways that differ in seemingly unimportant minor details. We shed light on these differences, explain their impact, and clarify for which games these notions coincide. Also we apply the same analysis to clarify the differences and similarities between various ways iterated elimination of strictly dominated strategies was defined in the literature.
