You don't have to have a destructive mind. Look at any mathematician, that's exactly what they do, find the exceptions to the "rule" and they don't call it a rule until they prove that there are no exceptions.
That's why mathematicians are gret security guys. This reminds me of these jokes:

I worked at a University for a long time and now I work for a bank with friends at all the major engineering companies around, from Microsoft and Google to IBM. The pattern is the same over and over, you see more foreign workers doing engineering in the US anywhere you go.
