When facing a difficult decision, individuals may rely on a coin flip to help them come to a conclusion. In some cases, however, individuals might not adhere to the coin's outcome, but instead report liking or disliking the coin flip's outcome, and may use this affective reaction to form their decision. In this manuscript we investigate the affective reaction towards the outcome of a coin flip and determine whether this affective reaction provides valid feedback in regards to individuals' underlying preferences (Hypothesis 1). We further test whether flipping a coin results in a higher alignment between previous preferences and subsequent decisions (Hypothesis 2). We conducted three studies in the lab and with online samples. Throughout all studies we found support for the notion that the affective reactions regarding the coin flip's outcome validly reflect previously indicated preferences or attractiveness ratings. Contrary to wide-spread expectations, however, we did not find reliable support for the notion that flipping a coin, compared to a control group, leads to decisions that are more in line with the previously stated preferences.
