For certain values of “knew”. Science has different epistemic standards.
The marketers knew it well enough that the scientists should have studied it. That they didn’t was a serious epistemic failing; it’s not clear that these different standards are better. Denying something on the grounds that you haven’t studied it enough and refusing to study it is almost a fully general counterargument.
