I'm not going to answer that, as you have access to the same tools for research that I do, and are welcome to post pointers to better evidence if you have them.

I will note that the way you framed this question is a wonderful example of what I refer to in the post as "self-esteem transactions" over text channels. Whether intentional or not, this comes across as a query crafted to lower the addressee's self-esteem ever so slightly.

"What planet are you from?" is the same sort of line, a little blunter.
