Until they start attaching lie detectors to patients or invent a machine that can tell them what I am thinking then psycology is as inaccurate as an online poll. Bear in mind that DUmmies overwhelm these polls, both psycological and online.
How about the fact that the majority of psychology ‘studies’ are based on college students who need cash. Their responses are then extrapolated to the entire population. That’s not science.
Most psychology is the patient themselves talking out their problem or adversity, working on changing their reaction to it and enjoying a new, positive consequence. The fact that the psychologist has a sheepskin and the appearance of professionalism simply aids the process - a human placebo.
