One of the most considerable drawbacks of DDC,
that has been recognized by scholars of bibliographical
classification systems, is the particular influence of
"western bias." The class Philosophy and Psychology
is one of the classes, divisions and sections of DDC
which feel much more the effects of "western bias,"
which is evident in particular in classes not yet revised.
Class 200-Religion, and its divisions and sections, for
instance, was almost fully dedicated to Christianity, its
history and sects, and only few sections of the division
290 were concerned with all the other religions.
