I wonder if many Americans read Science Fiction?
I found, growing up in a family who were avid SF readers, that my mind was opened to many different possible scenarios set in fictional universes but obviously applicable to reality. That reading made me consider the downsides of technologies and other social changes. And that's why I see pervasive and unfettered use of facial recognition quite disturbing.
These sorts of studies are executed in a vacuum of knowledge; they don't try to influence, but clearly they don't inform either (well, it isn't their job, is it?). I wonder if the same results would be observed if an equal number of serious benefits and major issues/disadvantages were listed before hand?
It sounds (from this reporting) like the skewing in favour of its use seen in the "refined questioning" added only beneficial usages as the scenarios. Obviously, having not seen the detail, I could well be wrong in this assumption. However, if right, that to me makes the study biased and ultimately unhelpful.
