Law of Reciprocity
Law of Reciprocity
It's the psychological obligation to give back when you receive something. It can work through genuine goodwill, but it can also be exploited as a tool of manipulation.
Details
The Law of Reciprocity is one of the six principles of persuasion proposed by social psychologist Robert Cialdini. Humans have a deep psychological norm ingrained in them: "if you receive, you must repay."
How the Law of Reciprocity Works
When someone does us a favor, we incur a psychological "debt." Not repaying this debt creates an uncomfortable feeling. This is a very powerful instinct formed as humanity evolved as social animals.
Positive Uses
The Law of Reciprocity is a cornerstone of maintaining society:
Exploitation in Dark Psychology
In Marketing
Free samples and free trials are offered to then drive purchases. The "door-in-the-face" technique — giving something small first and then asking for something big — also falls under this.
In Personal Relationships
A manipulative person does a small favor and then demands a much larger return. They weaponize past kindness with phrases like "Remember when I did that for you?"
In the Workplace
A boss gives a small perk (like allowing early departure) and later assigns excessive work, saying "I covered for you back then" — this is a common pattern.
How to Protect Yourself
Reciprocity is a beautiful social norm, but if it starts to feel like a burden or you feel taken advantage of, it's okay to say no. — Mindy
