  Somehow that seems to be pretty common with certain subject matters.

  For example, ask anybody, an expert or layman, why you can die from
touching an electrical wall socket (which has at most 230 volts), but
usually not from an electric cattle fence (which has tens of kilovolts)
and you won't get a straight, rational answer. I have yet to get a
proper answer from anybody (which wouldn't seem to violate the basic
"U=RI" formula).

  Or ask any physicist about the candle-in-a-glass experiment: You have
a plate with some water, and a candle in the middle. Light the candle,
put a drinking glass upside down on the plate so that the candle is inside.
When the candle goes out, the water will be sucked inside the glass. Why?
You will get approximately as many different answers as people you ask,
none of which will be correct.
