Purview of study. Study and participation are two different things. I don't know of any discipline that is immune to dick-wavers. Doesn't change the status of a science.
It does on a fundamental level. Pythagoras, Abu al-Nasawi and Isaac Newton can all agree on the fundamentals of Mathematics. Freud, Jung and Skinner can't decide whether it's sexual impulses, collective unconsciousness or biochemical reactions that are at the centre of Psychology.
Not to mention the rather unscientific methods they used.
Not true..? Well designed Psychological experiments not only marginalize but can even eliminate observer bias.
Impossible. You can get it down to statistically improbable, but the bias is still there in the computation.
Physics can't predict the movement of quarks (it can make strong guesses), but its not disqualified as a science.
Quantum Physics is as soft a hard science as they get. Observational bias directly affects Quantum, as Schroedinger states.
Psychology can make consistent predictions for trends and tendencies. Its not 100% accurate, but when dealing with the most complex subjects known to man (himself), you can't expect that sort of result with the methodologies currently in existence. Furthermore, dealing with humans as subjects leads me to argue that Psychology is the (if we resort to the dichotomy that you seem to be wed to) hardest of sciences.
Ok, if you are placing a challenge on the strength of the sciences; shall we make it a scientific challenge?
I'll derive Fermat's Last Theorem from basic principles. You can define Schizophrenia.
You can have 70 years head [

The hard sciences are characterized as relying on experimental, empirical, quantifiable data, relying on the scientific method, and focusing on accuracy and objectivity.
But at least you're not a sociologist. Brrrrrrr.
