Causation in Psychological Research
The European Journal of Personality just published an article by James Lee, titled
“Correlation and Causation in the Study of Personality”
European Journal of Personality, Eur.J.Pers. 26: 372-390 (2012) DOI:10.1002/per.1863.

or here.
Lee’s article is followed by Open Peer Commentaries

(Strikingly, the commentary by Rolf Steyer declares the do-operator to be self-contradictory. I trust readers of this blog to spot Steyer’s error right away. If not, I will post.)
Another recent paper on causation in psychological research is the one by Shadish and Sullivan,
“Theories of Causation in Psychological Science”
In Harris Cooper (Ed-in-Chief), APA Handbook of Research Methods in Psychology, Volume 1, pp. 23-52, 2012.

While these papers indicate a healthy awakening of psychological researchers to recent advances in causal inference, the field is still dominated by authors who have not heard about model-based covariate selection, testable implications, nonparametric identification, bias amplification, mediation formulas and more.
Much to do, much to discuss,
