Secrecy involves the active concealment of information from others, which can cause undesirable consequences for cognitive, perceptual and health psychology, but empirical research linking secrecy to charitable behaviors remains relatively scarce. This research examined whether secrecy weakens people’s desire to engage in charitable behaviors. Two experiments demonstrated that as a mental burden, secrets decreased people’s donation desire, including their intentions to volunteer and donate, and their tangible charitable behavior. In Experiment 1, recalling a personal secret increased the tendency to donate less money than recalling a neutral experience. Study 2 showed that this weakening effect of secrecy on charitable behaviors is mediated by fatigue (but not negative affect).

The current study assessed the burden associated with secret-keeping from confidants’ perspective. We proposed a cognition-affect-relationship model to explicate the interrelations between intra- and interpersonal consequences of confidants’ secret concealment. A total of 231 participants (Mage = 32.6 years) completed a survey on their experiences in keeping secrets for a close relational partner. A path model was conducted to test all hypotheses simultaneously. Results indicated that secret importance, valence, and negative face threat served as indicators of cognitive burden regarding secret-keeping. As predicted, cognitive burden was positively associated with negative affect. In addition, negative affect mediated the association between cognitive burden and relationship satisfaction, whereas secret characteristics were directly related to relational distancing. Overall, examining confidant burden provides insights on how secret-keeping might affect individuals and their relationships.
