I think that you are trying to attribute the differences between "browsing" and "searching" to biological differences between genders. Every single porn site that I've seen has layout very similar to Pinterest, so clearly, men enjoy hunting and pecking, or "floating around the page for interesting content" as much as women do.

On a related note, I sincerely hope you are not in a position where you interview women for positions that require systematic thinking (a.k.a. "jobs"). Personally, I'd hate to be on the other side of the table if that were the case.
