In an examination of domestic violence, you find only one article on the problem from a psychological perspective, but many from sociology. You should assume from this discovery that:

a. Sociology is more relevant than psychology in this investigation.
b. Psychology has written nothing important about this topic and should be dropped
from your research.
c. The one article produced by psychology on the problem may contain information
of such significance that an interdisciplinary understanding of the problem that is
truly comprehensive would not be possible without it.
