They’re not interested in “Truth”. Remember what was said in The Christian World View of Psychology and Counseling:

6. Scientific Method

We affirm that the scientific method is useful in carrying out the creation mandate of Genesis 1:28 to subdue and have dominion over creation when the investigators have Biblical presuppositions and when the Bible does not directly give us the answers we seek; that the use of the scientific method is entirely controlled by the presuppositions of the investigators and therefore the results are a pronouncement of faith rather than of scientific fact; and that the faith nature of the results of scientific investigation is evidenced by the investigators’ proselytizing intent, that is, their attempt to transform man into their idea of what man should be. We deny that the scientific method can ever be applied in psychology without its being thoroughly determined by the presuppositions of the investigators.

I’m actually heartened that so many “politically sound” psychologists don’t have truck with this philosophy. I apologise, but I’m surprised, frankly. I wonder how many other NARTH “scientific advisors” they considered? I’m sure Cameron would have been able to make up something that would be more to their liking, but perhaps they saw Rekers as being less tarnished.
