One of my habits while driving is to attempt to model the minds of many of the drivers around me (in situations of light traffic). One result is that when someone does something unexpected, my first reaction is typically "what does he know that I don't?" rather than "what is that idiot doing?". From talking to other drivers, this part of my driving seem abnormal.

In this sense, I model my parents strongly as agents–I have close to 100% confidence that they will do whatever it takes to solve a problem for me.

One of the frequent complaints about the 'agent' concept space, and the "heroic responsibility" concept in particular, is that it rarely seems to take into account people's spheres of responsibility. Are your parents the sort of people who would be able to solve anyone's problem, or are they especially responsible for you? Are other people that seem to be NPCs to you just people that don't care enough about you to spend limited cognitive (and other) resources on you and your problems?

With people who I model as agents, I'm more likely to invoke phrases like "it was your fault that X happened" or "you said you would do Y, why didn't you?" The degree to which I feel blame or judgement towards people for not doing things they said they would do is almost directly proportional to how much I model them as agents. For people who I consider less agenty, whom I model more as complex systems, I'm more likely to skip the blaming step and jump right to "what are the things that made it hard for you to do Y? Can we fix them?"

Do you get more of what you want by blaming people or assigning fault?
