Eric Trexler received his PhD in Human Movement Science from the medical school at the University of North Carolina, Chapel Hill. He is a professional body builder and a sports nutrition researcher, and the co-owner of Stronger By Science, MASS Research Review, and the MacroFactor nutrition app, as well as the co-host of the terrific Stronger By Science podcast. Robinson and Eric discuss some philosophical concerns in sports science, including methodological limitations in study design and human error in scientific reasoning. Among other topics, they address the ecological validity of mechanistic research, ways in which funding and practical constraints guide experimentation, and ethical considerations that factor into the study of steroids and other performance-enhancing drugs.
