Before participants enter a survey on Prime Panels or sign up for the Connect platform (and continuously while they are on the site), they pass through a proprietary data quality tool called Sentry. You can learn more about Sentry here.
How Sentry Works
Participants who pass through Sentry undergo a series of behavioral measurements designed to identify those who are attentive and engaged. Sentry also detects and mitigates fraud at the technical level with features such as CAPTCHA and device fingerprinting. Additionally, it enhances the quality of responses to open-ended questions, which are often a challenge in online research.
