At my first full-time job I had my own office. With a door! That closed! This was a 68-year-old academically influenced tech company, which believed you needed to give people private offices so they could do their best work. I hated it. I would come home each day, starved for social contact, feeling isolated and lonely. It turns out I need to be around other people during the day to be happy, and being in a room by myself just doesn't work. Since then I've worked in a series of open-plan offices, and while it can be a little harder to get heads down work done, I'm much happier.

(I think some of why I see lots of people expressing a strong preference for something I dislike is just that preferences for the status quo tend to be expressed less. But I think a bigger component is that I'm pretty much on the extreme end in terms of having a preference for other people being around. I don't need to interact with people while I'm working on things, I just want be in the same space. I've talked to lots of people who get sick of having others around, and need time alone; that's not something I've actually ever experienced.)
