In a study on decision-making, a researcher predicts that participants will be more risk-averse after viewing a sad film clip. The initial analysis shows a non-significant result (p = .12). The researcher notices high variance in the data and decides to exclude the 15% of participants with the slowest reaction times, justifying this by arguing they were inattentive. After this exclusion, the result is significant (p = .04).
