Hey everyone, I'm new the forum and a psychology student so I thought I would chime into this discussion. I'm always confused by when people such claims, especially considering there is an abundance of psychology research that can be considered in a true scientific sense, "law" of nature. Few examples that jump to mind is "reinforcement theory", "behavioral momentum" and "Matching law" but there are many more. I'm not sure why psychology is consistently being asked to defend itself as a science or why people do not believe it makes the same level of prediction as other sciences. To me it seems like anyone who has been reading up on and studying scientific psychology knows there have been incredible advances in the science and it is much richer and deeper than what the public perception seems to be.
Hey Imza, as I mentioned to you in an earlier discussion over at Ratskep, I think the problem here is just basic ignorance of what psychology is. People aren't interested in psychology because they think it's all wibbly discussions of the "unconscious" and wanting to have sex with your mother, and so they don't bother to read about the mathematical laws that underpin our thoughts and behavior.

Isn't this a bit unfair considering the nature psychological disorders don't lend themselves to "definitive" tests? It's not as easy as giving taking blood or other samples from a patient. Yes psychological disorders are complex and that's why it requires complex science to understand it, it's not as easy as simplifying it into definitive disorders when the state of nature is not that simple. That aside, it seems like your focusing on DSM diagnosis, which I will grant is not nearly as scientific as it should be, partly due to lingering influence of Freudian theories. However, if your talking about more general psychological assessments and tests, there is very strong scientific research to back up these assessments tools. Using anecdotal evidence of how different psychologists would give different diagnosis does not, in my opinion, prove or speak for the field as a whole. I myself have had clients who have had clearly been misdiagnosed but out of negligence of the clinician, not the failing of the scientifically based instruments or procedures.

Why are you using the DSM as a standard for judging the scientific basis for psychology? Unfortunately, the DSM has remained largely based on opinion and not on scientific data (which exists), despite the community of scientists trying to change the DSM. This is a problem for sure and it's being addressed, just see the uproar over the DSM 5, but it again doesn't speak to the scientific research in psychology. If one wants to claim scientific psychology is not scientific, I think the proper thing to do is to pick the strong research or studies in psychology and in detail describe why it's not scientific.
Whilst I agree with your confusion over why someone would appeal to the DSM to question the scientific validity of psychology, I think you're being a bit unfair to the DSM. The recent versions are becomingly increasingly based on scientific evidence, and the criteria listed within it have been refined according to the best available evidence. The problem, however, is that people tend to view psychological disorders as being biologically-based, so when people say, "No cause have ever been found for a single mental disorder", what they mean is that no concrete spot in the brain has been identified as the cause of OCD or whatever. The obvious flaw in this is that causes of many psychological disorders have been discovered and found, for example, some forms of phobia, PTSD, depression etc. The confusing part for some people to grasp is that there can be multiple causes to the same problem, and there can be different behaviors which are a manifestation of the same problem.
But, as you say, discussing clinical psychology is irrelevant in a discussion on the state of psychology as a science.

Psychologists do that too and even though I'm not sure what your intention is in bringing this up, I assume it's a criticism of a sort. I would again like to point out that the situation is different in psychological care, especially in cases where clients are suicidal or at risk for harm towards others among other situations that require "overturning patient rights". Anyways, I see this as a topic of bio/medical ethics rather than a failing of psychiatry/psychology.
His claim is also incorrect. Doctors routinely lock people up and put them in isolation when they contract contagious diseases to protect the life of the individual and society as a whole, and parents can be forced to hand over their children in order to receive life saving surgery or medical intervention when they refuse it provide it.
As you correctly point out though, even if it were true that psychology was the only health profession to do this, so what? It's a political/legal issue, and only related to clinical psychology, so it's confusing as to how it all relates to the science of psychology.
