The goal of this essay is to clarify positionality as an epistemological scientific concept and address related misunderstandings to help researchers assess whether statements thereof contribute to their work. Positionality statements can be useful …
Successful science needs deviant ideas that may challenge established norms. The last decade saw an unprecedented science-engineering project, with strict rules on preregistration, statistical testing, result-independent guaranteed publication, …

A study with low statistical power has a reduced chance of detecting a true effect, but it is less well appreciated that low power also reduces the likelihood that a statistically significant result reflects a true effect. Here, we show that the …
