Your sources are in error. Anyone can set up a web page which says

about
kidnappings by flying saucer which are about as reliable as the ones you
list.

Indeed, you can find a large number of supposedly-authoritative sources
about photography repeating the tale about light meters being calibrated
to 18% gray -- the fact that they aren't and never have been doesn't seem
to stop people from believing it.

Really? That's something I've always just accepted as true myself. Now
you've piqued my curiosity: how is the 18% tale wrong?

Isn't an 18% gray card really 18% gray? (I have one around here somewhere
but never thought to test its eighteen-percentness. :-) )
