Introducing Protocol: our multi-layer quality system
Quality participants over quantity
While competitors prioritise millions of participants over quality, Prolific is highly selective. We invite only 13% of applicants from our waitlist based on demand. After 50+ rigorous quality and identity checks, just 55% pass and can start studies and tasks.
Continuous fraud detection
Unlike other platforms, the checks don't stop. Ad hoc identity confirmation checks ensure no fraud, bots, or shared accounts. Our machine learning algorithms detect suspicious patterns across the pool, and our full-time quality team responds.
In-study quality assurance
Our proprietary authenticity checks detect AI-generated responses with 98.7% precision. Exceptionally fast submissions are automatically flagged and replaced.
Performance-based controls
Top-performing participants earn priority access to studies, and poor performers are excluded. Use our quality and skills-based targeting options to filter to high performers.
Motivated, engaged participants
Our industry-leading reward structure and policies have built a loyal participant community that delivers thoughtful responses and strong retention for ongoing projects.
