Abstract：This research aims to investigate whether other people who took a previously more attractive opportunity
would influence inaction inertia. Additionally, further discussion is included to focus on the influence produced by
anticipated action regret and value assessment on inaction inertia. Questionnaires and experimentation are used as
methodology to test the hypotheses in this essay. A total of 842 college students (375 males and 467 females)
participated in the research, with an average age of 21.77±1.98. Bootstrap of Mplus is used as the analytic method
to analyze and process the data.
The results indicated that: (1) Social comparison moderated the effect of chance comparison to action likelihood.
(2) Anticipated action regret mediated the relationship between chance comparison and action likelihood. Value
assessment mediated the relationship between chance comparison and action likelihood. (3) Anticipated action
regret mediated the moderation effect of social comparison. Value assessment also mediated the moderation effect
