There's not just a generational wealth gap anymore. There's a wellbeing gap too.

And right now, it's hitting younger people the hardest.

Ongoing human oversight and fine-tuning of our data quality systems is also crucial in protecting good participants and research integrity.

Our system benefits everyone. You get reliable data, and our valued participants enjoy a platform free from unfair competition.

We architect authentic data through Protocol, a state-of-the-art system that sets the industry standard for data quality. With five layers of defense, it ensures every response on our platform is authentically human.

Each layer is detailed in the full article.

We put authenticity above all else.

Independent research validates Prolific as setting the standard for data quality (2017-2025). Only 0.5% of Prolific participant responses were rejected in 2025. And a recent audit shows that just 0.99% of participants were flagged for AI-generated responses.

When you commission human data, you deserve human data.

Our commitment to data integrity remains constant. Protecting access to real human perspectives has been Prolific’s top priority since its inception in 2014.

Note that the tool doesn't automatically reject anyone's submission - researchers are advised to check responses and make an informed decision to approve or reject. If rejected, this doesn't result in a ban either unless the participant has a high number of rejections overall. Hope this helps.

Hi team, the false positive rate is 0.6%. We take every measure to ensure a very low false positive rate and provide extensive guidance, but if a participant feels they were incorrectly flagged or rejected, we advise they make their case to the researcher first, or contact support if unresolved.

In the age of AI, we’re committed to preserving genuine human insights that power impactful academic research.
