FGT You say that your friends discussion of a topic like this would result in something like
^"It’s more that I’d say something like the OP and they’d say “wow/goodness/really?” Followed by “where did you see that then?”
“Oh, on the tv this morning/in The Telegraph/the Daily Mail/the Euro weekly News”. Then we’d chat about it.
I suppose good natured lay agree it was shocking (or not) but never disputing the source(s)."^
Please don't get all offended by this - but when I read that, I couldn't help thinking that you and your friends sound like fertile ground in which the latest would-be "political influencer" journalist/agitator can plant the seeds of conversion to his party, view, attitude or conspiracy theory.
I don't have solemn analytical conversations when chatting to friends - but faced with the "fact" in the original post, their first reaction would be to ask how they counted these elusive creatures who were evading being noticed by all agencies. That is a minimal sceptical curiosity - "Who says so?"
If you and your friends never do that, you deserve to be conned - perhaps by a phone call from "Microsoft" offering to fix the "Fault" they have detected in your computer, if you will just follow this link and do as it says . . .
Is that so much different from in general having you believe someone without wondering how they know? After all, if you think about it, you know that Microsoft have no idea of your phone number or what make and model of computer you have, let alone whether there are any problems with it.
If you were not shocked by the news they give, you would have asked how they have your number, get theirs (probably faked, but at least you would have a chance of finding that out) for future reference, and have THEM tell YOU that you have a XXXX, model YYYY.
They rely on the "fact" being so overwhelming that your normal caution is overcome. So do the owners of media that specialise in sensationalist but unsourceable journalism. One of the hallmarks of it is the liberal use of words like "shocking" to get attention.
