Significance statement
STILL
Misinformation has become a severe social problem, and helping the public deal with it is a significant focus of psychologists’ research. One effective approach has been to use psychological inoculation to combat misinformation. Still, the comparative effectiveness of different forms of inoculation and their impact on the perception of accurate information needs further investigation. In this study conducted in China, we compared the effects of game-based and graphic-based forms of inoculation and analyzed their impact on the perception of accurate information and misinformation. We found that both forms of inoculation effectively reduced perceived credibility and sharing intention of misinformation, and the effects remained stable for two weeks. The game-based inoculation was more effective in reducing perceived credibility of misinformation than graphic-based inoculation. Neither form of inoculation impacted the perceived credibility and sharing intention of accurate information. These findings demonstrate the effectiveness of inoculation in combating misinformation and suggest that more active inoculation measures should be developed and applied.
