The vast majority of computer programming is done in "stodgy", "boring" settings, like offices and for government projects, so this really shouldn't be a surprise for that field. The "work anywhere when you like, just get your 8 in" concept is relatively niche, even in the Valley "glamor" bubble.
Exactly. According to Oracle there are approximately 9 million Java developers in the world, and since Java is the enterprise programming language, an awful lot of them are working 8-5 in a cubicle.
The American Time Use Survey only measures "paid work" which I assume excludes personal projects and most "night owl" activity other than being in operations/on call or having a particularly bad job.
The post I was replying to said they thought Computer and Math workers would be more night owls. Something that is really just based on the mothers basement late at night stereotype of those called geeks.
I was saying that IT workers just aren't that different than everyone else.
