Those are valid questions.

I simply found the phrasing “[quote of a sentence saying 35% of the time]. 35% of what?” to be funny because you would either have to not read the sentence you pasted or be an English speaker that does not understand what “% of the time” means.

I personally didn’t download the study linked in the article. It is interesting that they (must have, I’m assuming) did not include anything about their methodology in this study since they usually do with other things they publish.
