Here is the actual study: https://www.frontiersin.org/journals/psychology/articles/10....

They didn’t control for occupation, pay, managerial status etc.. An on-site physical job like nurse, facilities, or technician was compared to predominantly remote administrative jobs.

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.

They also completely fail to ask for the reasons of better well-being and then the article just starts guessing.
