Phantom costs are perceptions of hidden costs to an offer which seems too good to be true. Prior research on phantom costs has focused on an economic perspective, however, no prior research has studied phantom costs in the area of romantic attraction. The present paper addresses this gap in the literature. Study 1 shows the existence of phantom costs using a behavioural design, whereas the second study uses a vignette design to re-establish the presence of phantom costs, as well as shows that when given a sufficient explanation, phantom costs are mitigated.
