Exactly. The home office debate is a great example of motivated reasoning - many people really like the personal benefits of home office which makes them look for things which confirm their view (with the bar for "evidence" being very low).
The more passion you have, the more ridiculous form it takes. In normal debates, intelligent people usually admit that there are various trade-offs, and there are different POVs which might favor one trade-off over another. But in the home office debate, pro-HO seems to take a position that RTO cannot have any true, valid benefit, there's no real trade-off to be made, and therefore it can be explained only by ulterior motives or some conspiracy - usually hyper-controlling managers or this real estate conspiracy.
It's all guesswork until we start measuring the impact of interruptions in open plan offices vs. homes (which is going to vary with families).
It does feel like a debate that is mostly qualitative, and from two different sides (employee and employer).
My anecdotal experience has been that most employees I speak to are pretty clear about certain elements at the individual level but vary along many key axes: home office allows them to focus OR is too distracting; they miss the office culture OR hate the inefficiency of office smalltalk; they thrive on in-person connections OR thrive in focused isolation. There is also the topic of commuting, which most people don't love doing.
Employers should largely be motivated by more quantitative thinking, although in practice this varies and the metrics themselves are notoriously difficult to quantify.
