Though somewhat tedious to read the description of each tactic, this is a useful book. It forces one to think about how they influence others, and what other strategies might work better. It has made me think much more consciously about this. When one tactic doesn't work, change to another. The Influence Model posited by Bacon is based on TOPS (tactic, organizational power, personal power, skills). As a signal of another's preferred influence model, they tend to use the ones that also work best with them. As much as I like logic, the old maxim reared itself again: people decide on emotion and justify later via logic. Sources of personal power include: knowledge, expressiveness, character, attraction, and history.
