Do you have a link to the mentioned study?

Edit: nvm, I think I found it : http://journal.sjdm.org/15/15923a/jdm15923a.pdf

It was on HN before: https://news.ycombinator.com/item?id=17764348

But perhaps I wasn't clear, the study doesn't say this, but it was rather my own experience with the BS sentences in that study that led me to the observation that they have an empty set of examples if we take them as a constraint satisfaction problem of sorts.
