Baymard Institute — researcher-created FAKE trust seal raised perceived trust; displaying 6+ seals can trigger SKEPTICISM; most household-name brands omit them entirely

Claim: Baymard Institute's seal survey produced two findings that cut directly against trust-seal vendors:

• A researcher-created FAKE seal raised perceived trust in survey respondents — meaning the cue works on perception, not real-security verification.
• Displaying 6+ seals can trigger skepticism, with diminishing or negative returns past a threshold.
• Most household-name brands omit seals entirely, suggesting the dominant CRO-vendor pitch (more seals = more trust) is not borne out by what large operators actually do.

Source: Baymard Institute seal survey (self-funded via Google Consumer Surveys to mitigate vendor-incentive concerns).

Confidence: Single-source/Directional on the specific seal effects. Industry-consensus on the broader claim that seals manipulate perceived security rather than reflecting real trustworthiness.

Caveat: The badge finding cuts against vendors: trust-seal vendors sell on the premise that their seal causes trust. Baymard's fake-seal result shows the cue works at the perceptual layer regardless of provenance — which means cheaper or generic seals can produce similar perceived effects, undercutting the premium-seal sales pitch. Pair with Rule: use REAL transparency — clear contact info, disclosure, genuine outbound links (Nielsen's durable factors) — NOT seal theater; trust seals manipulate perceived security, not real trust.
