Other Face of Psychology

I remember someone telling me that they heard a physicist once say that psychology was a pseudo-science, but I don't remember who exactly it was that said this. Anyways, I was wondering if there's a consensus out there that supports this notion of psychology being a pseudo-science, and if so, why?
Well, I guess it depends on what you mean by pseudo-science. It shouldn't really need a consensus, it seems like a pretty straightforward question, is it scientific or is it some other form of academia?

As far as my experience goes with psychology and science I think it's on about the same level as Biology, I think the general principles of observation are the same, especially in bio-psychology. I think if anything your physicist has an issue with how psychology extrapolates a lot more than most other sciences, but I think that's inevitable given that the discipline is so very new (didn't really exist a hundred years ago - was a branch of philosophy).

Meh, I'm not a physicist, but I consider it just as legitimate as Physics, science or not.
When one is mentally deficient a psychologist can usually make diagnosis pending on their training and experience. I don't believe that through observation that a psychologist could ever truly diagnose chemical imbalances - for obvious reasons.

the common misconception of Jung's Collective Unconscious is probably more like mysticism- but the actual idea is more properly understood by the very real science of evolutionary biology- the Collective Unconscious [as well as synchonicity/ archetypes/ subtle correspondences] is merely mystical sounding description for a very physical idea: that many of a human's foundational conscious structures are NOT learned structures built uniquely for each individual during child development as was generally accepted during Jung's time- instead his colorful conjecture essentially shows that our most primitive fears and ways of thinking about basic survival are hard-wired adaptations that our species cultivated in it's genome over it's evolutionary history- so that each human would essentially have the same copy of these unconscious ways of thinking hard-wired into them at birth- the other part of Jung's idea is that this kludged black-box of hard-wired neural processes that we all share is responsible in part for the nature of human myths and metaphysics- this is because the 'collective unconscious black-box' has priority flight-or-fight brut survivability programs: be scared of the dark- be scared of snakes- embrace the light of the sun- look for pure water/food/resources- stay away from violent humans- trust calm humans- etc- all of these millions of little algorithms that are hard-wired for each of us and tell us how to react to very basic survival scenarios provided the basis for morality and ethics as well as all the creative mythical symbologies primitive humans developed to organize and implement these core concepts-

so there is nothing mystical about the collective unconscious in these terms- it is the folk interpretation that instead of each human possessing his own 'black-box' of adapted wiring that our 'souls' are connected in some kind of spiritual hyperspace in which the myths are real- and that we sometimes tap into it-

[although from the computational neuroscience perspective replicated copies of neuro-structure are fundamentally equivalent to a 'connection' in a 'spiritual hyperspace'- when notions of classical space-time are put aside and the observable information of a quantum system is dealt with directly: take away these metaphors and you can replace both with one: separate human instances of 'software' running independently but accessing a common set of information from a 'database' stored in the 'shared hard drive' of the human genome- where the process of reproduction copies the same database into each new human- in the context of information it does not matter if separate agents are accessing a central file [spiritual hyperspace]- or if each agent has a copy of the file [evolutionary neuroscience]- these are equivalent! ]
