Is it so hard to imagine that people who are home, surrounded by a spouse/so, perhaps children, entertainment systems, a fridge, a bed, no one looking at their monitor, etc... aren't on average more distracted?

I certainly am. We are only human.

I am equally distracted at home or office, just by different things. At home, kids, fridge, etc. At the office I lose time to the commute, to moving my car every two hours, to office conversations, etc. I burn time reading HN, watching basketball stats and researching roadtrips from either location so they even out.

I'm certainly not more distracted. Everything you've described is far less distracting to me than your average open office plan.
