Media literacy

Media literacy refers to the knowledge, skills, and dispositions needed to effectively evaluate, analyze, and create media messages across platforms. In the context of misinformation research, media literacy encompasses:

• Knowledge of media systems: understanding how news is produced, distributed, and monetized
• Critical evaluation skills: ability to assess credibility, identify bias, verify claims, and recognize manipulation tactics
• Healthy skepticism: the capacity for balanced doubt—questioning sources without descending into cynicism or dismissing all information as unreliable

Media literacy is often positioned as a solution to misinformation exposure, but its relationship to behavior and belief is complex and context-dependent.

Key tension: knowledge vs. confidence

A critical distinction in the literature is between actual media literacy (measured knowledge) and perceived media literacy (self-assessed ability). These often diverge:

• People who overestimate their own media literacy abilities tend to engage more with social media but critically evaluate information less—a problematic pattern
• People with higher actual knowledge of media systems tend to be more selective in what they consume and more skeptical of information quality
• Self-assessment of media literacy is a weak guide to actual critical thinking ability and may even be counterproductive if it breeds false confidence

• Jevin West — Misinformation and Data Literacy — educational interventions (Calling Bullshit course) and the asymmetry principle; emphasizes data literacy as a form of media literacy
• Mihailidis & Viotty (2017) — Spreadable Spectacle in Digital Culture: Repositions media literacy beyond fact-checking toward critical creation and civic engagement. Uses Pizzagate and Pepe memes during 2016 election as case studies. Argues that media literacy must address the structural conditions enabling spectacle spread (homophilous networks, meme culture) rather than treating spectacle as individual failures of discernment.

Finds 26.5% improvement in discernment in US, 17.3% in India online sample. Effects persist ~3 weeks but decay over time; no effects in low-digital-literacy rural sample.

• Does media literacy education without behavioral incentives translate to changed media consumption in the wild?
• Can skepticism generated by media literacy be maintained without fostering disengagement from civic discourse?
