I don't think a profile of a single woman doing this study is any kind of proof that only women do this kind of study. Your premise and your reasoning are not aligned with reality.
It's clear to me now that the message I intended to send and the message that was received were very different. My original comment was made half in jest, along the lines of "I always knew my wife was mad, but now I have proof." The other half of my comment that was not meant to be humorous was simply acknowledging that similar jokes would likely not be told if circumstances were different.
