Idiot correlations
November 19th 2009 11:47
Economists love to invent stupid theories of how 2 completely separate things are correlated. They believe (and make believe) that when you compare 2 variables and, after some basic math, check that they are "correlated", you can guess the value of one by having the values of the other.
Models like these for example find that the expenses in beer and evolution of the GDP of a country a correlated; the number of rock songs in the Rolling Stone 500 best songs of all time and the production of oil are correlated; etc.
Well, I'm a fashion victim as well: I've just noticed, after 5 years of deep study on the matter, that 80% of the serial killers of the world eat bread for their breakfasts. So next time you'll be interviewing someone to do some babysitting for your kid, remember to ask what they eat in the morning...
cheers.
