Altruistic behavior refers to actions taken by individuals that involve a personal cost but benefit others, yet research has been influenced by “loss aversion.” To mitigate this interference, the study employed the Altruistic Personality Self-Report Scale to measure subjects’ level of altruism and utilized a “next double” social experiment paradigm with different amounts and types of social pressure. Results indicate that higher monetary incentives tend to lead subjects towards self-interest, while under social pressure they tend to choose altruistic interest. This study effectively reduces the impact of “loss aversion” on evaluating altruistic behavior and provides new insights into understanding its dynamic mechanisms.展开更多
