It's not just exhausting, it's a huge problem. Even if everyone is a complete saint all the time and has the best of intentions, going by beliefs about beliefs can trap us in situations where we're all unhappy.

The classic situation is the two lovers who both want to do what they think makes their partner happy, to the extent that they don't tell what they actually want, and end up doing something neither wants.

I think the goal of all sorts of cooperative planning should be to avoid such situations like the plague.
