To elaborate on this a bit: I have started to suspect that the practice of nounifying verbs in a professional setting, like "learnings", is a subtle leading indication that somebody will be trying to deflect responsibility or escape accountability.

The phrase "what can we learn" has a locus of responsibility in it, a set of humans you can point to next time and say, we should have known better.

"What are the learnings", notably, does not.
