Absolutely.  An excellent example of a theory that is sound but is found
disconcerting by the establishment would be George Kelly's work (1955).  
Essential to Kelly's personal construct psychology is the metaphor of 
the "person as scientist".  While this elevates lay-people to the lofty 
position previously only held by academics, it also threatens the 
prevailing order by being too radical and thus has been largely ignored 
or even misconstrued by mainstream psychology.
Kelly's work (like Jung's) may perhaps actually be a psychology way 
ahead of its time with its emphasis on idiographic analysis and a
qualitative understanding of the processes that give meaning to 
people's lives.  Hopefully with the growing emphasis on alternative and
constructivistic methods, Kelly's work will finally be acknowledged 
in the mainstream for the unique perspective that it represents.
Also, the person as scientist implies a "power to the people" approach 
which has never suceeded as a movement historically even in democracy.
Graham, you may be interested in this sociology of science approach to 
pcp.  BTW, my paper is on its way to Vista U.  Best Wishes.  Hemant
