In a survey by Nature (Baker, 2016), 52% of respondents from different disciplines stated that there is a significant crisis in the reproducibility of research results. Possible reasons for this include falsification of studies, questionable research practices, insufficient power of studies, lack of statistical literacy, or too simple (correlative) hypotheses for complex empirical phenomena....
Jingle and jangle fallacies arise from unclear connections between theory and empirical studies. In jingle fallacies, different phenomena are given the same name, whereas jangle fallacies occur when the same phenomenon is given different names. This problem has only been increasingly studied in recent years, although these fallacies have been known since Thorndike and Kelley. Examples of...
