Discover each person's thumbscrew
Everyone has the lever. Most go unused.
Discover each person's thumbscrew is Greene's thirty-third law. It describes the idea that every person has a weak spot, an unmet need, a fear, a vanity or a craving for approval, and that whoever finds it gains a lever over them.
The observation is uncomfortable but familiar. Advertisers target insecurity about looks or status. Scammers target loneliness, greed or fear of missing out. In ordinary persuasion, understanding what someone truly cares about explains why some arguments land and others do not. Many attempts to convince people fail simply because they address a concern the listener does not have.
The serious ethical limit is who you apply this to. Using someone's insecurities against them, especially a friend, partner or colleague who trusts you, is manipulation, and it destroys trust and your own reputation once noticed. The constructive version is empathy: learning what matters to people so you can meet real needs and avoid hurting them.
The strongest use of this law is self-defence. Know your own thumbscrews. If you are susceptible to flattery, urgency or guilt, write that down. Then, when a seller, a recruiter or an online stranger suddenly presses exactly that button, you will recognise the pattern and slow down before you decide.
Example
You get an email saying your account will be closed within the hour unless you confirm your details. You know urgency is your weak spot, so you stop, open the official app directly instead of the link, and find no warning at all. The message was designed to press that exact button.

Write down two of your own pressure points, such as flattery or urgency, and decide on one pause rule for when you feel them pressed.
