There is a highly amusing TV quiz here in the UK, called QI. One section of the show is called "General Ignorance", and consists of asking apparently easy questions, with answers that "everyone knows", but in fact they know incorrectly. The audience has great fun watching the participants answer with obvious, but totally wrong, answers.
- How long did the Hundred Years War last? (Answer, 116 years)
- Which country makes Panama hats? (Answer, Equador)
- From which animal do we get catgut? (Answer, horses, sheep or cows)
- Puffinus Puffinus is the scientific name of what bird? (Answer, the Manx Shearwater)
Beware of General IgnoranceI wrote yesterday about the maturity trajectory of knowledge – how knowledge passes through stages of maturity; from discovery, to exploration, to consolidation, to embedding. An exciting new idea passes through the stages, to become established knowledge; something “everybody knows”. Everyone knows the earth is just one planet in a solar system, everyone knows how an internal combustion engine works, and everyone knows that you need to wear a hat in the winter, because you lose most of your heat through your head.
Except, in the last case, you don’t. You don’t lose any more heat through your head than you do through any other part of your body. That’s one of the things “everyone knows” wrongly. This is knowledge that has got stuck somewhere on the Maturity chain, and has become common knowledge (or general ignorance) before it became truth.
In Knowledge Management, we need to beware of the things that “everyone knows”, and occasionally we need to challenge them. Maybe they are not correct, maybe they got stuck somewhere down the chain, or maybe the context has changed and the knowledge is out of date.
For example, everyone knows you put the milk in the cup before you add the tea, but people used to do this to sterilise the milk, and all our milk is pasteurized. Similarly someone told me recently that you mustn't pick blackberries near busy roads for fear of lead poisoning, but who uses leaded petrol nowadays?
Communities of practice, and practice owners, need to be vigilant for general ignorance, and be prepared to challenge perceived wisdom. Just because "everyone knows" that (for example) that the Canary Islands are named after yellow birds, doesn't make it correct.
