I've just finished responding to an alleged "survey" conducted as part of a PhD student's work in pursuit of that award.
The document itself was little more than a "vegan" propaganda rant, dismissing any contrary view by simply not allowing non-supportive responses. The "researcher" climed for instance, that the reason that we call cow-meat "beef" is purely commercial - were it called "cow" people would see the light and become vegans.
This type of survey is unfortunately not uncommon. So much for the value of the qualifications obtained from grants from the public purse - to say nothing of the "validation" it provides for future researcher able to cite Dr. Jo One-eyed's 2014 study which found...what was intended to be found.
So I wondered whether there was a term for such surveys. I'd be tempted to call it an Appleby for obvious reasons - but why coin a term when there's a perfectly good one already?
