Introduction to the Special Issue on Mediation Analyses: What If Planetary Scientists Used Mediation Analysis to Infer Causation?

Mediation analyses have become extremely popular in the social sciences generally, and in social psychology specifically, because they seem to grant the researcher the ability to draw causal conclusions from correlational data. But this is illusory. Correlation provides poor quality evidence of causation not only in the case of zero-order correlations but also in the case of more complex mediation analyses. The articles in this special issue provide compelling arguments as to why mediation analyses make a weak case for actual mediation. My goal is to cognitively prime the reader for these articles by presenting analyses pertaining to the mean orbital momentum, kinetic energy, and conversion energy of the eight planets of our solar system. Our solar system provides a dramatic case in point where mediation analyses provide blatantly wrong conclusions.
