Claim LD10-HQ-C03 (v1.0)
In one UK experiment, about 36%–42% of GPT-4o's immediate attitude effect remained at a one-month recontact.
Research opportunities this claim motivates
What this claim leaves open for research. Each is a hypothesis about a gap, not a finding.
- Does weeks of everyday AI-answer use make people check sources less?The only persistence estimate in the debate is a one-month recontact for persuasion, which shows how short current follow-up horizons are; it does not license claims about durable change.
