> The failure and successes of the response should be distinctly studied to determine a better course of action for the next pandemic.
For sure. I bet the authors agree. But wouldn't one necessarily need to answer "Did X meaningfully change during the pandemic?" before answering "How much of that change is attributable to which specific causes?"
This is a finding answers the first question and makes it a lot easier to fund research into the second. Every political strategist, economist, sociologist, historian, epidemiologist, and public health official wants answers to the same questions as you -- even while some anticipate a different answer than you might.
It just takes a minute to get there and there's some preliminary research to publish along the way.
