What are the dis-advantages of non-experimental research?

Answer:

What gives non-experimental designs its advantages actually contributes to its disadvantages. Since they are easy to conduct, many doctoral researchers do not put enough effort into exploring extant literature for what has already been done on the subject and often conduct non-experimental research on a whim. In addition, non-experimental designs often suffer from common method bias, specifically single-source bias, because collection of both dependent and independent variables from the same source is so easy and convenient.
