 Our discussion of the trickery and pressure accounts highlights a rather striking fact: If we survey the tactics that seem intuitively to be examples of manipulation, we find tactics that seem best described as forms of trickery as well as tactics that seem best described as forms of pressure. This is puzzling, since, on the face of it, trickery and pressure seem rather dissimilar. What should we make of the fact that we use the same concept—manipulation—to refer to methods of influence that seem to operate by such dissimilar mechanisms?
