Forking paths problem

The garden of forking paths is a problem in frequentist hypothesis testing through which researchers can unintentionally produce false positives for a tested hypothesis through leaving themselves too many degrees of freedom. In contrast to fishing expeditions such as data dredging where only expected or apparently-significant results are published, this…
