The "Shopping Cart Theory" as a test of your self-governance readiness got a lot of mileage over the last year (https://medium.com/be-unique/the-curious-case-of-the-shopping-cart-theory-802909d93cff) but a much more visible barometer came this year: the simple mask.

Not wearing a mask? Completely lacking in empathy
Mask under their nose? Possible reserves of empathy...maybe
Mask wearer? Exceeds the bare minimum
