The positions were filled from an applicant pool whose members largely believed in X, having graduated from schools and attended professional conferences in which X is regarded as a professional good if not a virtue, even though, for most people, X is still far from a settled subject.
The applicant names were obtained from a supposedly neutral recruitment agency which was, in reality, devoted to X. The agency intentionally sought candidates who were favorable to X.
The recruitment agency in turn was funded by a non-profit organization that promotes X.
And yet outside observers (and the employers) believed that their new employees were neutral on the subject of X and would be objective in evaluating other opinions.
True story. We live in interesting times.
