边际不诚实: 添加 10 任务

Marginal dishonesty, or the 'fudge factor,' occurs when people cheat just enough to gain resources without severely compromising their moral self-image. For example, a salesperson might report selling a few more cars than they actually did rather than the entire lot. This balances the external reward of extra money against the internal reward of still viewing oneself as honest, resulting in limited rather than maximal cheating.

The Adding-to-10 task requires participants to identify two numbers in a matrix that sum to 10 within a 4-minute period. Participants are told random winners receive $10 per correct answer. In the experimental condition, participants self-grade and self-report results with no verification, creating opportunity to cheat. Comparing self-reported scores to researcher-graded control scores reveals the extent of dishonest inflation.

Control group participants have their workbooks collected and graded immediately by the researcher, eliminating cheating opportunity. Experimental group participants self-grade their work and self-report results on a separate sheet that won't be verified, creating incentive and opportunity to inflate scores. This design isolates the effect of self-reporting on dishonest behavior while controlling for actual task performance.

Results show experimental participants reported significantly higher scores than controls, but most cheated only marginally with slight inflation rather than claiming maximum correct answers. This distribution demonstrates that people weigh two competing motivations: the external reward of money encouraging dishonesty, and the internal reward of moral self-image that caps the lie and prevents excessive cheating.

Moral priming reminds individuals about honest concepts and actions, decreasing their willingness to cheat. When students signed an honor code contract before completing the Adding-to-10 task, no significant difference emerged between their reported scores and control group performance. This suggests that prompting people to recall their institution's values and their own commitment to honesty effectively discourages dishonest behavior.

Placing mirrors in areas where people might steal, such as supply closets, increases self-awareness and discourages taking items. When individuals observe their own actions, they become conscious of whether their behavior aligns with their desired honest self-image. This self-reflection makes potential thieves realize that stealing contradicts their moral identity, reducing the likelihood they'll take items home.

External rewards, like cash prizes, motivate people to cheat and gain additional resources. Internal rewards, such as maintaining a positive self-concept, create competing motivation to remain honest. The interplay between these forces determines dishonesty levels. People balance the benefit of external rewards against the cost to their moral self-image, resulting in limited cheating rather than maximum exploitation of unethical opportunities.
