Earlier i quoted Michael Crichton:
This fascination with computer models is something I understand very well. Richard Feynmann called it a disease. I fear he is right
Clifford Stoll cuts to the heart of why this is so:
Computers hide mistakes in logic while sanctifying information with an aura of truth.
(Sorry, i wrote down the quote but failed to get the proper citation. It's from several years ago, probably from Silicon Snake Oil.)
A model will spit out reams of information and data. It seems so concrete and precise: percentages are calculated to two decimal places.
Yet deep in the unseen guts of the model are a bunch of WAGs and SWAGs put there at 1.30 in the morning by analysts desperately trying to make their deadlines.
