For these four research is not needed

‘If you have a hammer, everything looks like a nail.’ Similarly, if you a research skill, every problem may look like a research problem. Though it is possible to research any problem, it may not be necessary to do so. The following examples verify this fact.

There is enough evidence to act
If there is enough evidence to start action, then you need to act. Unless one rules out the presence of enough evidence, research may not needed at least at the start up stage. Enough evidence is enough!

Evidence is unlikely to be used
If evidence is unlikely to be used for different reasons, then there is no need to generate more evidence unless one wants to waste resources. There may, of course, be a need to generate evidence after creating sufficient ability to use it.

Absence of evidence doesn’t justify inaction
If absence of evidence doesn’t justify the absence of action, research may not be necessary. Instead, the other factors that explain inaction, need to be addressed.

No evident demand for evidence
Research shouldn’t be conducted just for the sake of research. There has to be some level of demand for research. In the absence of evident demand for evidence, research outputs may not be used.
