Gratitude inhibits competitive behaviour in threatening interactions

It is well established that gratitude favours prosocial tendencies in neutral and amicable social interactions. Less is clear, however, about the role of gratitude in threatening situations that breed competitive impulses. As gratitude inhibits self-centred impulses and motivates a communal orientation, we predict and demonstrate that gratitude reduces competitive behaviour in threatening interactions. In Study 1 (N = 171), after emotion induction, participants went through the classic Trucking game paradigm, whereby a bogus opponent behaved in a competitive manner (i.e. closing the gate on them). Gratitude, as compared to joy and a neutral mood state, reduced participants’ competitive behaviour against the opponent. In Study 2 (N = 422), after losing to a bogus opponent on a self-relevant task, participants were given an opportunity to sabotage the opponent’s chances of winning a lottery. Individuals induced to feel gratitude showed less sabotaging behaviour than those in a neutral mood state. Importantly, this effect was only observed against a highly competitive, but not a neutral, opponent, suggesting that gratitude inhibits competitive behaviour only under high threat. Our findings suggest that gratitude is instrumental in arresting the competitive cycles from developing in threatening social interactions.
