There is nothing called 'real' science. There is hard science and soft science. Psychology and such matters are part of the soft sciences....and obviously their methodologies will be somewhat different from those of the hard sciences.
Wrong: it is all science, where methods will be suited to what is being studied, and if it is indeed 'science' it will involve an approach using the discipline of the scientific method since, if not, then it isn't 'science' - it would then be 'pseudo-science', which is no good to anyone except those who use it to exploit the gullible.
Thus psychology, as would be studied by academic institutions and documented in accredited peer-reviewed journals, is no less a 'science' than, say, physics even if professional psychologists rarely require access to the Large Hadron Collider.
