One can use a hammer as a screw-driver, but most of us would realize that's a waste of time.

"Scientific analysis" of morality as a statement of what we "ought to do", for example, is nonsense. OTOH, what might be open to scientific scrutiny is, for a few examples,
1) examination of brainwave activity in humans (on micro level)
2) activity of humans acting in various situations
Both of these examples clearly fall under psychology, neurology, or sociology.
