RMT 21:1 Notes and Quotes

False Concreteness

Peter Drucker described years ago ... "the illusion of false concreteness." This is believing that a result or recommendation presented with figures showing multiple decimal places is somehow more accurate than a judgment call presented in words alone.

Clinical Significance

"Evaluations of the outcomes of psychological treatments are favorably enhanced when the published report includes not only statistical significance and the required effect size but also a consideration of clinical significance."

Kendall, P.C. (1997). Editorial. Journal of Consulting and Clinical Psychology, 65, 3-5.
