It has been suggested that research faces a “reproducibility crisis”, in that many claims that appear in research papers may be exaggerated or even false. A not insignificant (shall we say) component of this problem is the heavy reliance in scientific publication on the concept of statistical significance. A “significant” p-value provides a licence to make a scientific claim or report a “finding”, so it is not surprising that researchers feel a strong compulsion to find and report small p-values. This presentation will review the dangers associated with over-reliance on statistical significance as the currency of research and discuss concepts such as the probability of a false positive claim, and Type S and Type M errors.
