Correlation is not Causation

Clever post by TheAtlantic.com blogger Megan McArdle:

"I'm forced to conclude that (the import of) Mexican lemons have improved highway safety a great deal. The vitamin C, maybe? The fragrance? Bioflavanoids?"

Read the short article, featuring a great graph, with near perfect correlation of increasing lemon imports and a reduction in US highway fatalities

A great reminder to ask the right questions about some of those problematic security surveys and studies that are being churned out at high rates with low integrity.

"What's the mechanism?" is one good question to ask.


PS I'm not partisan when it comes to information security, so McArdle's political spin is her own.
