In a recent Economics Explained video "Emergency PSA - The End of YouTube in Australia" at 0:27 and 5:39, there was a claim that a specific Australian policy may have been timed to be announced while the general population was distracted by the COVID-19 pandemic.
The Guardian claims in Take Out the Trash Day – the perfect opportunity to bury bad news that the UK government buries bad news while people are distracted by Christmas.
Jo Moore suggested taking advantage of the September 11 attacks to release bad news, but it seems to have been a major blunder.
It sounds like a plausible hypothesis, that governments deliberately announce unpopular policies or release bad news when the population is distracted, but I'd like to know whether the hypothesis has been critically examined, and if so, what the conclusions are.
