Grandiose narcissism influences the phenomenology of remembered past and imagined future events.

Little empirical work has examined future thinking in narcissistic grandiosity. We here extend prior work finding that people scoring high in grandiosity have self-bolstering tendencies in remembering past events, and we consider whether these tendencies extend to imagining future events. Across an initial study ( N  = 112) and replication ( N  = 169), participants wrote about remembered past events and imagined future events in which they embodied or would embody either positive or negative traits. Participants then rated those events on several subjective measures. We find that people scoring higher in grandiosity remember past events in which they embody positive traits with greater detail and ease than past events in which they embody negative traits. These same effects persist when people scoring high in grandiosity imagine possible events in their future. Those scoring higher in grandiosity endorse thinking about positive events in their past and future more frequently than negative events, and they judge positive future events as more plausible than negative future events. These tendencies did not extend to objective detail provided in their written narratives about these events. Taken together, these findings demonstrate that grandiosity is associated with self-bolstering tendencies in both remembering the past and imagining the future.
