I think your comment is deeper than it seems. Working on the right thing to make progress can be REALLY REALLY HARD. It can be so easy to fool yourself by doing the task you know how to do instead of the one that needs to be done, working on the task that feels good, working on the task that brings personal benefit, focusing on the thing that everyone else seems to be doing and so on. Heck, marketing departments the world over put enormous effort into A/B testing which may seem very scientific, but is often little more than p-hacking and cherry picking. Was the field of psychology making progress for 50 years before the replication crisis? Possibly not as much as it would seem. Did medicine make any progress before germ theory? Not much! And we fundamentally have the same brains as the people who espoused humoral theory, so we have an undiminished capacity to fool ourselves. Worker beware!
