The Half-Life of Facts

Stephen Fry of the BBC's Quite Interesting reminds us of the eroding certainty of knowledge.

Easily my favorite game show is the BBC’s Q.I. (a.k.a. “Quite Interesting”), hosted by the planet’s honorary ombudsman, Stephen Fry.  I guess you’d call it a trivia quiz.  But really the object is for the four panelists, usually comedians, to be interesting, to be witty – even more often than they’re correct. 

A recent episode was themed around the Half-Life of Facts.  Essentially, the program’s creator, John Lloyd, went back through the show’s earlier seasons and collected knowledge which has since been proven inaccurate.  Once, for example, the host reported that there was no way to accurately tell the age of a lobster.  But by the time of this Q.I. retrospective, marine biologists had learned that the lobster’s eye stalk was the key to dating it.
