Software Testing Paradoxes

I've found an interesting article in MSDN magazine. It describes several paradoxes that can occur during software testing process.

1. Simpson's paradox demonstrates that conclusions of several data sets can differ from conclusions of a combined data set. Thus, the test result summary does not necessarily represents the same as the original uncombined data.

2. Braess's paradox may arise during network performance testing and states that adding capacity to a network can actually reduce the performance.

3. Parrondo's paradox assumes that when combined, two completely independent but faulty systems can make up a correct system.
