Concept
Appeal to Self-Interest
Appealing to self-interest is Law 13 of Robert Greene's The 48 Laws of Power: when you need someone's help, show them what they gain from giving it, rather than relying on their gratitude for the past or their mercy toward you.
Greene's examples are envoys who failed when they reminded a ruler of old favours and succeeded when they showed him a concrete advantage. The underlying point is plain and largely ethical: people act most reliably when the action serves something they care about. Gratitude fades, and pity can make the asker look weak. Dale Carnegie made a gentler version of the same argument: talk in terms of the other person's interests. The honest use is to do the work of understanding what the other side wants before you ask, and then to frame your request so that it genuinely delivers some of it: the manager who wants fewer escalations, the client who wants to look good to their own board. If you cannot find any real benefit for them, that is useful information too; the request may be unfair, or the wrong person may be receiving it. The defensive reading is to notice when someone appeals to your self-interest with gains that are vague, inflated or not theirs to give.
A real-life example
Zeynep, an HR specialist in İzmir, wants budget for a mentoring programme. Her first proposal talked about employee wellbeing and got no reply. The second shows the operations director that two of his teams lost four people last year and estimates what one mentoring cohort costs against one replacement hire. The director co-signs the proposal.
How to use it
- 1Before asking for help, write one sentence on what the other person gains from giving it.
- 2Make the benefit concrete: a number, a problem removed, a result they can show.
- 3When someone promises you a gain, check that it is specific and that it is in their power to deliver.
