Why we cite it
Provides experimental evidence across four studies that a simple linguistic reframe — "I don't" instead of "I can't" — significantly improves people's ability to resist temptation. The mechanism is psychological empowerment: "I don't" grounds refusal in identity and personal choice, while "I can't" signals deprivation and external restriction. A longitudinal field study confirmed real-world applicability. Directly supports the project's identity-based approach to food decisions.
