Don't Trust Me, I'm an Expert

Max Planck having won the Nobel Prize for physics in 1818, was a celebrity in the scientific community and went on tour. His chauffeur, who had heard Planck's speech so often he could recite it suggested that in Munich, they swap places and Max should watch, wearing the chauffeur cap, while the Chauffeur delivered the speech.

At the end, another physicist stood up and asked the Chauffeur a rather detailed and specific question. The Chauffer laughed and and said: 

"That question is so basic, I think I'll let my Chauffeur answer it!."

Cool story eh?

Don't just trust people who claim they know things. They may only appear to know things.

Got it?

Except, you are doing it right now, aren't you?

You are taking the Chauffeur story from me at face value. 

I've looked on the 'net, and can find no record of the Chauffeur Incident. I can find examples of several people claiming it is true - each of them an 'expert' in their field.

Long story short. Don't assume people are telling you actual empirical truth. Even those people, like me, who tell you not to.
