  When statisticians quarrel about hypothesis testing, the debate usually focus
on which method is the correct one. The fundamental question of whether we
should test hypothesis at all tends to be forgotten. This lack of debate has
its roots on our desire to have ideas we believe and defend. But cognitive
experiments have been showing that, when we do choose ideas, we become prey to
a large number of biases. Several of our biases can be grouped together in a
single description, an opinion bias. This opinion bias is nothing more than our
desire to believe in something and to defend it. Also, despite our feelings,
believing has no solid logical or philosophical grounds. In this paper, I will
show that if we combine the fact that even logic can never prove an idea right
or wrong and the problems our brains cause when we pick ideas, hypothesis
testing and its terminology are a recipe for disaster. Testing should have no
place when we are thinking about hypothesis.
