Abstract: The phenomena known as the ambiguity of time cost, the unsteadiness of time perception and the heavy bias towards the present, indicate that people make irrational temporal decisions. Major influential factors of irrational temporal decision-making include mental accounting, decision context, cognitional factors and individual factors. As proposed herein, monetization of time, rational analysis, imagined regret, team decision, suitable time scheduling and cultural knowledge are considerations which help to reduce irrational decision-making. Further studies can investigate the influences that subjective perceptions of time and high technology have on temporal decision-making as well as the socialization of temporal decision-making. Future research can also be conducted considering various perspectives from other disciplines or by trying a new paradigm.

Key words: temporal-related decision-making, irrational, mental accounting
