Scientists rise up against statistical significance

nature

Let’s be clear about what must stop: we should never conclude there is ‘no difference’ or ‘no association’ just because a P value is larger than a threshold such as 0.05 or, equivalently, because a confidence interval includes zero. Neither should we conclude that two studies conflict because one had a statistically significant result and the other did not. These errors waste research efforts and misinform policy decisions.

    by definition, there will be statistical values which will not suggest a causal relation, but in fact are and vice versa. The signatories have not offered an alternative system or how to fix errors in the existing system, just some possible alternatives.
