When University of Texas professor Mark Regnerus released a study this summer portraying gay parents in a negative light, he insisted that the conservative funders who backed the research had no involvement in how it was designed, implemented, or interpreted. But recently emerging evidence shows that a scholar affiliated at the time with the Witherspoon Institute — the socially conservative think tank that supplied the bulk of Regnerus’ funding — did indeed play a role carrying out and analyzing the study.
