People like those like them, who like them.
To influence people, win friends, through: Similarity:Create early bonds with new peers, bosses, and direct reports by informally discovering common interests—you’ll establish goodwill and trustworthiness.Praise:Charm and disarm.Make positive remarks about others—you’ll generate more willing compliance.
People repay in kind.
Give what you want to receive. Lend a staff member to a colleague who needs help; you’ll get his help later.
People follow the lead of similar others.
Use peer power to influence horizontally, not vertically; e.g., ask an esteemed “old timer” to support your new initiative if other veterans resist.
People fulfill written, public, and voluntary commitments.
Make others’ commitments active, public, and
voluntary. If you supervise an employee who should submit reports on time, get that understanding in writing (a memo); make the commitment public (note colleagues’ agreement with the memo); and link the commitment to the employee’s values (the
impact of timely reports on team spirit).
People defer to experts who provide shortcuts to decisions requiring specialized information.
Don’t assume your expertise is self-evident. Instead, establish your expertise before doing business with new colleagues or partners; e.g., in conversations
before an important meeting, describe how you solved a problem similar to the one on the agenda.
People value what’s scarce.
Use exclusive information to persuade. Influence and rivet key players’ attention by saying, for example:“…Just got this information today.It won’t be distributed until next week.”
