As a biologist, I can say that most statistical errors are just that: errors. They are not tricks. If researchers understand the statistics that they are using, a lot of these problems will go away.

A person has to learn a hell of a lot before they can do molecular biology research, and statistics happens to be fairly low on the priority list for most molecular biologists. In many situations we are able to get around the statistical complexities by generating data with very little noise.
