Masks as a moral symbol: Masks reduce wearers' deviant behavior in China during COVID-19.

Area of Science:

• Behavioral Ethics
• Social Psychology
• Public Health

Background:

• Mask wearing became widespread globally due to COVID-19.
• The psychological and behavioral impacts of mask-wearing beyond health benefits are largely unexplored.
• Understanding mask-wearing's influence on everyday behavior is crucial.

Purpose of the Study:

• To investigate the effect of mask-wearing on deviant behavior.
• To test competing hypotheses: masks as disinhibitors (anonymity) versus moral symbols (awareness).
• To provide empirical evidence on the behavioral consequences of mask usage.

Main Methods:

• Employed 10 studies with mixed methods, including observational and experimental designs.
• Utilized large-scale data analysis (n = 68,243) from sources like traffic cameras.
• Measured various forms of deviant behavior, such as traffic violations and academic dishonesty.

Main Results:

• Consistently found that mask-wearing reduces deviant behavior.
• Evidence supports the hypothesis that masks act as moral symbols, heightening awareness.
• No support was found for the hypothesis that masks increase anonymity and disinhibition.

Conclusions:

• Mask-wearing positively influences behavior by enhancing moral awareness.
• The findings extend beyond the health benefits of masks, revealing significant psychological effects.
• This research offers novel insights into the social psychology of mask usage.
