You truly are an outlier. I immediately started assuming that you might be in a more right-brain role, but realized my mistake when I saw your comment about coding. You're clearly better than I am at focusing...
I can _code_ while surrounded by interruptions and distractions (I can put on headphones and face the least busy part of the office so I'm not _too_ distracted most of the time), but I can't _learn_ without some semblance of focus. I suspect that the open-office cheerleaders are mostly people who do the sort of work that you or I might be able to do on autopilot and never try to tackle any sort of real challenge.
