Abundant research has shown that people fail to disregard to-be-ignored information (e.g. hindsight bias, curse of knowledge), which has contributed to the popular notion that people are unwillingly and unconsciously affected by information. Here we provide evidence that, instead, people simply do not want to ignore such information. The findings: in Studies 1 & 2 the majority of participants explicitly indicate a desire to use to-be-ignored information in classic paradigms. In Study 3, the effect of receiving to-be-ignored information is driven entirely by the subset of people who want to use it. In Study 4, convincing participants to ignore inadmissible evidence in a mock jury paradigm is shown to reduce the impact of such evidence by convincing them to plan to ignore it.
