Amazing displays of ignoranceSandettie Light Vessel Automatic tells us: "My dad's friend told us there's no such thing as gravity - it's just the weight of air holding us down". Tell us of times you've been floored by abject stupidity. "Whenever I read the Daily Express" is not a valid answer.

Security risk: PIN contains "numbers"We had some relatives to stay recently, including an aunt's husband who I've never had much chance to speak to before. He's amiable enough, but it quickly became clear that trying to develop a logical argument about *anything* was a complete mystery to him.
My favourite thing that he told me was about a security problem inherent in bank cards that use a PIN for authentication, because "often, the numbers used for the PIN are also printed on the card itself". I questioned what he meant by that, preparing to show him an array of bank cards that don't have the PIN printed on them, but it turned out he just meant that the four digits that make up the PIN can sometimes be found — individually, randomly — among the other numbers on the card.
He was convinced that this presented a security risk, as criminals could use these "clues" to work out the PIN and steal your money.
