I find “believe” and “feel” to be more natural in relation to a fact which is still under investigation. As more affirmative samples come in, I feel and believe more strongly in its truth. “Conclude” implies conclusion, where no further evidence is needed, and where no evidence to the contrary is expected. The history of science suggests the vast majority of results are not conclusive. So maybe this language is not entirely a measure of rational vs emotional, but also a measure of confidence. Nevertheless, I think the conclusion of this article probably is correct.
