Snyder and Swann (1978) demonstrated that individuals systematically adopt confirmatory strategies and preferentially search for evidence that confirms existing beliefs. We suspect that Snyder and Swann’s results are an artifact of their methodology. In the present experiment, we replicated Snyder and Swann’s work, but had participants generate their own hypothesis testing questions instead of selecting questions from an existing list. Results did not replicate those of the original study.
