d. They may indicate different directions for theoretical ideas.

The negative results could be a true reflection of reality. In this case, the reasoning of the researcher or the theory used by the researcher to develop the hypothesis is in error. Since this was a huge multi-site interventional study, it establishes the fact that the intervention does not work with a sizable number of clients. This is useful to know.
