Tell a lie long enough, people will begin to believe it. Even without any evidence to support it. Even in the face of evidence that actually disproves it. Think of the movie "Expelled" with Ben Stein; the documentary of how dogmatic academia and our society, really, are in regard to the presumption of evolution even though there's never been any evidence to support is main presumptions. The same reaction is found when questioning the validity or daring to think outside of the dogma of psychology.
Both evolution and psychology are related. Because evolution devalues human life to that of mere animal which developed over eons of time from a primordial soup, believing we are nothing more than the sum of material (cells), there was left a gaping hole as to how to deal with the inner man; the emotions, thoughts, and spirit of the individual. Enter psychology. Psychology is the daughter of evolution, and the studies done under the guise of "science" (always biased, and funded by pharmaceutical companies who need to make money and by researchers who need the companies to fund their research), involve animal trials.
We are not animals. We are created in the image of God.
Gen 1:26 Then God said, "Let us make man in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth."
Gen 1:27 So God created man in his own image, in the image of God he created him; male and female he created them.
Gen 1:28 And God blessed them. And God said to them, "Be fruitful and multiply and fill the earth and subdue it and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth."
