It's a good time to point out that Reason didn't publish the study, they simply referenced it in a blog post. Who did publish it? Here's one of the authors: >Gibson has published well over 100 refereed articles and chapters, in a wide range of national and international social-scientific journals, including all of the leading political science journals. He has also published eight books, including the award-winning Overcoming Apartheid: Can Truth Reconcile a Divided Nation? In 2009, Cambridge University Press published his Overcoming Historical Injustices: Land Reconciliation in South Africa. His three South African books – Overcoming Apartheid, Overcoming Historical Injustices, and Overcoming Intolerance in South Africa (co-authored with Amanda Gouws in 2004) – trace the evolution of South Africa’s democracy in the post-apartheid era, and have become known as Gibson’s “overcoming trilogy.” His Citizens, Courts, and Confirmations: Positivity Theory and the Judgments of the American People (co-authored with Gregory A. Caldeira) was published in 2009 by Princeton University Press.
