This study found that intervention videos have a significant positive effect in challenging gender bias in STEM fields.

By triggering emotional resonance and changing cognitive attitudes, intervention videos can effectively enhance public

support for gender equality, especially in large-scale dissemination and cross-cultural communication, and the video

form of visual narrative demonstrates the unique advantage of breaking through language barriers and enhancing

resonance. However, some limitations remain regarding audience acceptance, dissemination scope and long-term

impact. Further analyses show that video content with a straightforward narrative, highlighting female scientist

role models and emphasising gender equality, is more likely to be recognised and disseminated by viewers. With

the development of new media technology and increased attention to gender issues, intervention videos will play

a more important role in promoting women’s participation and development in STEM fields.
