It's my understanding that sociology and economics are mingled topics.
Those who profess to be sociology scientists are different than those who identify themselves as scientists of economics, because most who understand economics know it's more an art than it is a science. Sociology on the other hand addresses topics of culture, ethnicity, and other societal topics such as race, intelligence, ethics, and such. Many theories proposed by social scientists make claims that are found on ignorance, such as "why blacks are not intelligent."
Sociology also studies human economic activities that may have some value; such as why investors invariably buy high and sell low. During the recent market downturn, many sold their stocks (from fear); it was the wrong move as was proven by last week's rise in the market.
I'm not trying to imply that all sociological studies are wrong; but some of the research and their results are based on personal bias that is not worth the paper it's written on.
