Is Psychology Scientific?

Simply stated, science is the systematically arranged knowledge of the material world which has been gathered in a four-step process: 1) observation of phenomena; 2) collection of data; 3) creation of a hypothesis or theory by inductive reasoning; and 4) testing of the hypothesis by repeated observance and controlled experiments…Psychology rarely deals with established facts or truths but with subjective opinions and interpretations of uncontrolled observations. Psychology is not dealing with the consistent interactions between chemicals that can be carefully controlled in the laboratory, but with analyses that are tainted by the unique free wills of the subjects and the mindset of the researchers.
