Thanks. The complete gap to measure at-home living conditions kicks this into a flawed study. It does not control for physical living conditions anywhere. For instance, if your home is just some hot and filthy room in a neighborhood with lots crime, you're RTO just to escape the horrible environment.

Exactly. I support remote work, but purely as a question of science, it may not be a direct causal link between remote work -> happiness. There may be other factors at play.
