A new study examined who is most likely to complain in restaurants and reports that age and gender play little role in whether people complain. The findings challenge the popular “Karen” stereotype, which is often associated with a specific demographic.

The coverage from multiple outlets focuses on the same headline claim: that complaining behavior is not predictably linked to commonly assumed traits such as being older or being a particular gender. Both sources present the study as evidence against the idea that restaurant complaints primarily come from one recognizable group. While the outlets differ mainly in tone and framing—using the “Karen” reference to emphasize the stereotype being overturned—they describe the underlying message consistently: the likelihood of complaining does not appear to track with age or gender in the way the stereotype suggests.

Details such as the study’s methods, sample size, and exact measures of “complaining” are not provided in the supplied summaries, so they cannot be independently assessed here.
