The "economic uncertainty" sounds like something everyone would agree on. "Yes we are in uncertain times right now". Then again, at any point in time, there would be agreement that economy is in uncertain times. It is a meaningless argument because in my opinion it is always true.

Here is a Google Trend for "economic uncertainty", where nothing seems to have changed much except maybe little blip during Spring of 2020: https://trends.google.com/trends/explore?date=all&q=economic...

Edit, found a link which actually does show heightened economic uncertainty: https://fred.stlouisfed.org/series/USEPUINDXD perhaps contradicting myself.
