Revenge bedtime procrastination
From 52 things I learned in 2020:
報復性熬夜 is a Chinese term that roughly means 'Revenge bedtime procrastination' -- when "people who don't have much control over their daytime life refuse to sleep early in order to regain some sense of freedom during late night hours". [Lu-Hai Liang]
Oh, I do that. #psychology

Voter turnout
I remember thinking (and maybe saying) this after Trump got elected in 2016, but it's even more true now:  The one good thing Trump has done is to increase people's interest in politics, both local and national, and for both political parties.  This can be clearly seen in voter turnout percentages, which have been in the 50s and low 60s for the past hundred years or so.  The 2020 election saw a 66-72% eligible voter turnout, which is the highest its been since the 1800s.  Say what you want about him and his presidency, but a healthy functioning representative democracy requires the interest and involvement of the voting populace.  Mission accomplished. #politics
