PSYCHOLOGICAL AND COGNITIVE SCIENCES Correction for “Higher social class predicts increased unethical behavior,” by Paul K. Piff, Daniel M. Stancato, Stéphane Côté, Rodolfo Mendoza-Denton, and Dacher Keltner, which was first published February 27, 2012; 10.1073/pnas.1118373109 (Proc Natl Acad Sci USA 109:4086–4091).
The authors note that on page 4088, right column, first full paragraph, line 19, “SE b = 0.18” should instead appear as “SE b = 0.10.” The other statistics are correct. This error does not affect the conclusions of study 7 or the article.
