Participant fraud is intentional deception in research participation, usually to qualify for a study or collect an incentive. It can include misrepresenting experience, role, product usage, or demographics, hiding location or identity, participating more than once through multiple accounts, or using automation to submit responses.
Fraud is hard to spot because the output can still look like credible research on the surface. The risk is that the evidence is not just noisy, it can be directionally wrong. When teams treat fraudulent responses as real customer reality, they can ship changes that solve a problem that does not exist, miss the one that does, and lose trust in research altogether.
The goal is to protect the quality floor so the evidence stays decision-grade, especially in surveys and other high-scale, unmoderated methods.
