The central tendency bias is a robust finding in data from experiments using Likert scales to elicit responses. The present paper offers a Bayesian perspective on this bias, explaining it as a natural outcome of how participants provide point estimates of probability distributions over the items on a Likert scale. Two studies are reported that support this Bayesian explanation.
