<p>And I’m saying that’s inherently misleading, because if we use your definition, psychology is more quantitative than mathematics, because mathematics is by definition not science. Either the quantitative nature of subject is drawn from the mathematics involved, or it’s not. If it’s the former, economics is more quantitative than psychology, because my point is that economics uses way more math than psychology, and thus being more quantitative. It it’s the latter, then mathematics is not quantitative. </p>
<p>It won’t be preposterous of me to declare that there’s no popular usage of “quantitative” that’s not associated with mathematics. It’s one thing to say psychology is more scientific, it’s quite another to claim it’s more quantitative.</p>
