Sounds like there's no misrepresentation at all. Most people treat it as to become delusional of their own abilities or qualities, so functionally they are just tricking themselves in addition to everyone else.

"Changing your mental state" can be just as harmful as outright faking and sometimes there's no difference in outcome at all.
