I don't think it's really wrong to say most are sensitive to external indications of others' internal experience. Simultaneously, as you point out, we're often pretty bad at inferring intentions from this information. But we have much more than zero idea what's going on, in most cases; the amount we know and our level of certainty could be viewed as a function of cultural context, group cohesion, cooperation/competition under stress, individual differences, power dynamics, social norms, etc. > It even spawned a saying: "We judge others by what they do; we judge ourselves by what we intend." There is much evidence for an effect like this in social psychology, commonly called the fundamental attribution error.
