Well.... that's perfectly okay for the layman; but for the scientist, their efforts studying a subject are supposed to culminate in
thesis defence. That means the academic has to
advance the argument (or research) they believe is showing results (or that they think will show results).
The most obvious case in point here is materialistic and non-materialistic views of consciousness. While materialists might work on neural-networks and attempt to
advance the argument that consciousness is merely Information Processing and non-materialists might work on psi-experiments and attempt to
advance the argument that consciousness is distinct from matter/energy, the layman could simply throw his arms up in the air and say they don't care either way or that they don't know enough about the subject.
So, you have to "believe" in something if you want to do real science/research.
(You could
try a thesis defence of "I don't know either way"/"I can't make up my mind"/"I'm frightened of getting ripped appart by skeptics if I choose to say that robots are conscious or psi exists" (but please fund me anyway because one day I might get a set of b*lls or have a clue about what I'm doing), but I don't think any panel of experts would be too impressed!
