Back to the Present: How Direction of Mental Time Travel Affects Similarity and Saving
研究发现，从未来回到现在的心理时间旅行方式，能增强人们对不同时间点自我的相似感，从而小幅但系统地提高储蓄意愿和行为。
Abstract Many consumers say they want to save for the future yet struggle to do so. This research examines this saving behavior problem from a persuasive messaging standpoint. With the goal of helping people take better care of their future selves, we build on a stream of research that has found that the way people view their identities over time affects the saving decisions they make. Although past research on similarity judgments across time almost exclusively starts with the present self and moves forward to the future self, such judgments could theoretically start at any point in time. Here, we explore the possibility of backward mental time travel, by asking people to start in the future and return to the present. A series of studies shows that mentally traveling from the future to the present—rather than the present to the future—increases perceived similarity between selves across time by reducing the uncertainty of the destination self. Lab studies and two large-scale experiments indicate that, as an important outcome of this novel intervention, mentally traveling from the future to the present has a small but positive impact, systematically increasing savings intentions and savings behavior.
