Well, I would note that reading other folks doesn't necessarily require a situation be hairy, or even at immediate risk of it. People read each other all the time in non-hairy situations, like reading people they care about (or at the very least are on fine terms with) to find out what they're really feeling or what they would want them to do. The "charge" in that case is not suspicion or hostility. Hell, in one session in the campaign where I play an angel, our faceless was turning down a perfectly good meal, so I read him to figure out what was going on. Turns out it wasn't because it was the cannibal chef doing the cooking (the food in this case was not people, as far as we were aware) or that he wasn't hungry; he just didn't want to take his helmet off to eat. I made up some bullshit favour to ask of him that would involve him going off dealing with some shit out of sight and handed him a plate, and off he went. In other situations, you may want to ask if someone is lying not because you don't trust them per se, but because they're making an extraordinary claim or asking you to take a risk. And so on.
In another thread, lumpley noted that the non-coercive, non-socially-violent move for getting people to do what you wanted them to do was read a person. So perhaps sometimes the charge really is as simple as, "I don't know how to get Person Y to do X thing, and I want to know."
Of course, the risk is that if you blow your roll in a non-hairy situation, the MC has the opportunity to make it into a situation that is as "charged" as they like, in whatever way they like.
