We attribute intentions to others all the time. With business and even personal relationships increasingly conducted via e-mail, voice mail, faxes, and conference calls, we often have to read between the lines to figure out what people really mean. When a customer writes “I don’t suppose you’ve gotten to my order yet . . . ,” is he being sarcastic? Is he angry? Or is he trying to tell you that he knows you’re busy? Without tone of voice to guide us, it is easy to assume the worst.
