1960Q2-1960Q3 - GDP grew, yet this is flagged as a recession.
1981Q3-1983Q1 - GPD grew consistently the entire time, yet this is one of the longer recessions on record.
1990Q3-1991Q2 - GDP only dropped for one quarter, then quickly rebounded, yet it is flagged as a long recession.
2020Q1-2020Q1 - This is flagged as recession, despite being less than a single quarter. By "two consecutive quarters definition, this recession started in 2019Q4 and lasted until 2021Q1. Yet the NBER doesn't flag it this way. If they were "playing politics," they would definitely have made this out to be a larger deal.
It's pretty clear the NBER has never relied entirely on GDP data to determine recessions. Otherwise, there wouldn't be so many recessions with GDP growth.
