Without knowing the experiment details (number of trials, ratio of people laying vs telling the truth) we don&#x27;t know if 50 is actually significant. What&#x27;s the curve of success for participants assuming random guessing (in line with the proportion of liars)? Is 50 to be expected?<p>My first thought is that with 20,000 participants, sheer chance will give you a handful of outliers, and 50 at 80% accuracy doesn&#x27;t sound very high unless there were a very large number of trials per participant.
