The Like Switch
by Jack Schafer
A former FBI behavioral analyst explains how to make people like and trust you: the friendship formula (proximity, frequency, duration, intensity), friend signals like the eyebrow flash and head tilt, and the art of listening. It is practical, slightly manipulative in places and useful for anyone who finds first impressions hard.
Read it if…
you struggle to connect quickly with new people and want concrete signals to use.
Skip it if…
you dislike technique applied to relationships; the book is explicit about it.
Three things you will actually use
- Send friend signals before you speak.
- Increase frequency and duration gradually.
- Make the other person feel good about themselves.
Do this first
Use the friend signals, eyebrow flash, slight head tilt, genuine smile, with three strangers today.
Our verdict
Practical and specific; useful tools, used with care.
