Variety‐Seeking Tendency in Choice for Others: Interpersonal and Intrapersonal Causes
研究发现人们为他人选择时比为自己选择更追求多样性，这源于人际责任（需对选择负责）和个人内部机制（认为他人更快厌倦重复消费）。
Ratner and Kahn demonstrated that individuals believed that others would seek more variety than they themselves would seek. Building on this finding, we expected the variety-seeking tendency to be greater when people made choices for others, and we examined the mechanisms of this phenomenon. Study 1 explored an interpersonal mechanism and demonstrated that variety seeking for others became stronger when individuals were held accountable for their choices. Studies 2 and 3 explored an intrapersonal mechanism and showed that because of “focusing,” people expected satiation with repeated consumption to occur more quickly for others than for self. Implications and future research are discussed.
