Researcher degrees of freedom
Concept of flexibility in process of conducting a research study
Researcher degrees of freedom is a concept referring to the inherent flexibility involved in the process of designing and conducting a scientific experiment, and in analyzing its results. The term reflects the fact that researchers can choose between multiple ways of collecting and analyzing data, and these decisions can be made either arbitrarily or because they, unlike other possible choices, produce a positive and statistically significant result. The researcher degrees of freedom has positives such as affording the ability to look at nature from different angles, allowing new discoveries and hypotheses to be generated. However, researcher degrees of freedom can lead to data dredging and other questionable research practices where the different interpretations and analyses are taken for granted Their widespread use represents an inherent methodological limitation in scientific research, and contributes to an inflated rate of false-positive findings. They can also lead to overestimated effect sizes.
