Digital Advertising Stigma Salience Amplification
RCTClinical Trial
Deploying anti-stigma messaging in brief, low-touch digital advertisements backfires by triggering negative salience without providing sufficient engagement depth to dispel the underlying social stigma, causing significant reductions in program sign-ups.
Picture this
Imagine scrolling rapidly past a social media ad that says "Don't be embarrassed to take an entry-level job!" Because you glance at the image for less than a second, your mind registers the word "embarrassed" and links it to the job offer, causing you to scroll past even faster rather than pausing to read the positive graduate testimonials.
What the evidence says
Professional stigma ads reduced program sign-ups by 26% (-0.032 percentage points, p < 0.001) and social stigma ads reduced sign-ups by 39% (-0.047 percentage points, p < 0.001) relative to control (0.121% sign-up rate), proving low-touch ad formats amplify stigma salience.
- Who was studied
- N = 767,768 young adults aged 18–34 in Greater Cairo, Egypt (Facebook Field Experiment).
- How
- Large-scale Social Media Randomized Split-Test comparing control recruitment ads with professional and social stigma testimonial ads, validated with 1,000-iteration Lee-bounds style manual re-balancing.
What to do
Avoid using anti-stigma messaging in brief online advertisements, reserving stigma-mitigation campaigns for high-touch, in-person outreach.
