@KapoleiJoe has an interesting comment.  Fox engages in "population thinking," which focuses on variability.  When Fox talks about the "collective psyche" what interests her is the increase in ideas and beliefs that were formerly rare.  This represents a change in variability, or in her words "shift in our collective psyche."

@KapoleiJoe engages in "typological thinking", which focuses on the central tendency (or essence).  For him, the essence of the collective psyche hasn't changed and, from his perspective, this is proved by Trump's electoral college victory.   In this view, population thinking is "gobbledygook".

Alongside typological thinking, philosophers have found population thinking to be a powerful tool, which I doubt will go away.  If Fox's generation takes it up with more enthusiasm than @KapoleiJoe's, which seems likely, then from a population thinking point of view our collective psyche will have shifted.
