Any ordinary dictionary will tell you that psychology is the 'scientific study of the mind and its activities' . However, in reality, much of psychology is not scientific - at least not those studies which are based on evolution theory or any other theory which is godless in its assumptions. It has to be a guess, because no-one knows what the mind is, where it is, or how it works. We know that the brain is a physical entity - but we definitely do not know what 'mind' is. Anyone who claims otherwise is either a liar or deluded.
Many scientific studies appear to find links between the brain and what the 'mind' produces.
Thus, like evolution 'theory' itself, the studies are only at fundamental, 'unfinished-hypothesis' level. Thus, anything based on evolution or humanistic ideas is automatically in error. This is because what God says is absolute and true. Then, when it comes to interpreting all the data, there is a gross failure to allow the facts to speak for themselves. There is nothing wrong with providing a speculative interpretation of data collected by social or laboratory observation.
