"People fiercely resist any effort to make them change what they do. Given how bad they are at writing programs, one might naively expect programmers to be eager to try new approaches. But human psychology doesn’t work that way, and instead programmers will find any excuse to dismiss an approach that would require them to learn something new. On the other hand, they are quick to embrace the latest fad (extreme programming, templates, etc.) that requires only superficial changes and allows them to continue doing things basically the same as before. In this context, it is only fair to mention that people working in the area of verification are no less human than programmers, and they also are very reluctant to change what they do just because it isn’t working."

This is an excerpt from an answer about program verification. It's worth the read.
