Info stat: sharp. It's not enough to open your brain -- you need to open your eyes. This apocalypse isn't about mystic visions, it's about concrete details: the way a particular flower blooms, the symptoms of malnutrition, the archeology of abandoned buildings. If you want to know what's going on, pay attention to people: to what they want and why they want it. Everything happens for a reason, you just need to put it all together.
Default stat: hot. When push comes to shove, you have to depend on other people -- they're the ones who are going to save you, or leave you out in the cold. Not only that, there's almost always people around -- and even the guy shooting at you is willing to listen to an offer. It's the friendly people who get ahead, or the beautiful ones; everybody wants to be the one they rely on. But it's also the ones who understand people, who know how to build relationships and play off all those old fears. In the end it all comes down to leverage -- and everybody's got at least a little.
It's tempting to be glib and say: oh look, it's modern civilization. But of course lots of people (myself included, as Johnstone can attest) play AW as though the above were actually what was going on -- constantly reading situations and people, constantly trying to negotiate with the psychotic mutant raiders. You know the type.
