SpeedOfDark: Real scientists are human beings too, and they can believe in virtually anything! Hell, that's actually the point of science: have a hypothesis, and maybe spend your entire life trying to work with it. What distinguishes the "real" from the "unreal" (that's for Om Cheeto

) is what a scientist DOES and will admit.
Beyond that, jarednjames has you dead to rights, and in a fit of irony too because what you're saying is anything except scientific. You can't just make a broad sweeping statement that relies on... what you believe. I know, this must be weird coming from the same sources that are always skeptical, but that's PART of skepticism.
You need to entertain notions, explore them (see how DaveC will play devil's advocate sometimes when the science runs thin?), and then hopefully mounting evidence begins to support or refute your claim. Still, if your science is good, you follow the method and are open to full peer review... you can believe in unicorns.
Now, if you just said, "In my view, you can't have a scientific mind and believe in Chi at the same time." I'd still disagree, although I don't believe in chi, but you'd have just let us know what you think. Frankly, a LOT of people might think the same, or they might give extra scrutiny, but that's a GOOD thing. Science and art are all about the end product: if it's beautiful in art, or if it works in science (more to it of course) then the artist or scientist can be a lunatic.
If it's real science, others will be able to come along and by NECESSITY as part of the method, re-create the results. If not, does it matter what the beliefs are, and if so... does it matter what the beliefs are?
