The Wickedness of Covid-19
"In planning and policy, a wicked problem is a problem that is difficult or impossible to solve because of incomplete, contradictory, and changing requirements that are often difficult to recognise. It refers to an idea or problem that cannot be fixed, where there is no single solution to the problem; and "wicked" denotes resistance to resolution, rather than evil. Another definition is "a problem whose social complexity means that it has no determinable stopping point". Moreover, because of complex interdependencies, the effort to solve one aspect of a wicked problem may reveal or create other problems." Wikipedia
This sounds exactly like our response to Covid-19. Some will no doubt argue that actions taken or not taken are correct - from the point of view of their professional knowledge; but no one person or body can comprehend the full social/economic/menta/wellbeing effect of it all.
Even when this is done and dusted, we will never know if we've taken the right actions. All we can do, as at any point of decision, is make the best decision we can at the time.
