- Human experiment — Multi-study package: observer ratings (Study 1), correlational survey (Study 2), primed incremental vs entity beliefs with a rigged matrix cheating task (Study 3), and four-condition belief manipulation with a hiring discrimination task (Study 4).

- Chinese adults recruited online and Chinese undergraduate/postgraduate students
- Outcome
- Perceived likelihood of immoral acts, discrimination against a hepatitis B carrier in a hiring vote, and cheating (self-reported solved unsolvable matrices and money taken)

Key findings
Observers expected the 'changeable morality' person to act immorally more often, with medium-to-large effects. Stronger incremental beliefs weakly predicted more discrimination. Students primed with the malleable view reported about twice as many solved (actually unsolvable) matrices and took more than twice as much money as those primed with the fixed view. In Study 4, the malleable condition discriminated more than both fixed-belief conditions and the untreated control, which did not differ from each other.
Methodology
In Study 1, online participants judged whether a person who sees morality as fixed or one who sees it as changeable would be more likely to behave badly. Study 2 measured people's own beliefs and their tendency to vote against a highly qualified job applicant who carried hepatitis B. Study 3 randomly assigned students to read a fake science article saying morality is genetic or malleable, then gave them unsolvable number puzzles with cash per 'solved' puzzle and let them pay themselves. Study 4 manipulated beliefs by telling students their university's moral standing was stable-high, stable-low, or average and mixed, compared with a no-manipulation group, and then measured hiring discrimination.
Limitations
The proposed mechanisms (tolerance of one's own wrongdoing, protecting moral self-image) were never measured, so why the effect occurs is untested. Samples were Chinese and mostly female, the Study 4 effect was small, and the outcomes were ambiguous, low-stakes situations where cheating was unobserved, so the effect may not hold when wrongdoing is clear. Study 2 is correlational with a single scenario, and the Study 3 manipulation check was given before the outcome, which may have made the belief more salient.
