Studied ambiguity?

For what it's worth, I gather from the Tax Prof Blog that the artificial intelligence program at Gender Analyzer rates this blog as (only?) 61 percent likely to be written by a man, making it the closest to gender-neutral among a group of tax blogs other than the Tax Prof Blog itself, which comes in at 52%. Then again, two of the tax blogs come out opposite from the correct answer, perhaps saying more about the AI model than about the particular bloggers involved.
