In turn, psychology draws its authority from its claim as a social science. I don't think so. Two of the standard criteria demarcating science from pseudo-science are its ability to make risky predictions and its falsifiability. If a theory makes possible the forecasting of events that would not have been expected, one must surely stop and take notice. Falsifiability is important because, if a theory can tell us things to look for that would indicate that the theory is false, then we have a means of checking it against reality.
Counselors are neither able to predict with certainty nor to make falsifiable claims.
Nor does it contain any predictive force. Such stuff is not the material of science. Notice that counselors cannot offer you any certain results. At best, they tell you that they MAY be able to help you-and may not be. A fortuneteller can give you just about as much in the way of predictive force.
