Which evidence supports the reasearchers hypothesis?

The evidence that a researcher decides to use should be from a credible source and should be track-able.

It can or cannot back the hypothesis created by the researcher. In both cases, the researcher must synthesis it properly into his research. It must build a connection and somewhat extends the points discussed in the hypothesis.

Either way it should have a direction. Something that does not connect to the core of research must not be added in it.
