The English Accent That Makes People Think You Are Lying, According to Science

In this video, we break down the 2020 Frumkin study where 90 participants watched the exact same eyewitness testimony—only the accent changed. The result? Received Pronunciation (RP) speakers were rated as significantly more credible and accurate than Birmingham accent speakers. Same words. Same face. Different voice. We also explore the "processing fluency" effect—why your brain works harder to understand certain accents and then misinterprets that effort as a lack of truthfulness. Plus, the 2025 Cambridge study that found British people still associate working‑class accents with criminal behavior, and how this bias affects courtrooms, hospitals, and job interviews. If you speak with a regional accent, this is the most important video you'll watch this year.
