Bias

The idea
Bias is anything in a study's design, conduct or reporting that systematically moves its results away from the truth.
In practice
A study whose groups differed before the intervention began.
Where people slip
Bias is systematic, not random. It pushes a result in a direction, which is why more participants does not correct it.
