PSYCHOLOGICAL AND COGNITIVE SCIENCES Correction to Supporting Information for “Relational mobility predicts social behaviors in 39 countries and is tied to historical farming and threat,” by Robert Thomson, Masaki Yuki, Thomas Talhelm, Joanna Schug, Mie Kito, Arin H. Ayanian, Julia C. Becker, Maja Becker, Chi-yue Chiu, Hoon-Seok Choi, Carolina M. Ferreira, Marta Fülöp, Pelin Gul, Ana Maria Houghton-Illera, Mihkel Joasoo, Jonathan Jong, Christopher M. Kavanagh, Dmytro Khutkyy, Claudia Manzi, Urszula M. Marcinkowska, Taciano L. Milfont, Félix Neto, Timo von Oertzen, Ruthie Pliskin, Alvaro San Martin, Purnima Singh, and Mariko L. Visserman, which was first published June 29, 2018; 10.1073/pnas.1713191115 (Proc Natl Acad Sci USA 115:7521–7526).
The authors wish to note the following: “In the supplemental materials, the original paper used a measure of indigeneity to represent historical ethnic diversity and mistakenly labelled this heterogeneity. The updated supplemental materials correctly label this indigeneity and add a different measure of historical diversity—the number of source countries for the AD 1500 population. Data from Palestine was left out of the earlier analysis because the source data combined it with Israel. The new analysis adds Palestine. New results show that historical indigeneity remained a nonsignificant predictor of relational mobility (r = −0.19, P = 0.240), while the number of historical source countries predicted higher relational mobility (r = 0.55, P < 0.001).”
As a result of this, the authors have updated the section 1.10.1 Historical Ethnic Diversity in the SI Appendix, page 23. The SI Appendix has been corrected online.
