provenHow strong is the evidence?

Tested again and again, by different people, and it keeps coming out the same. You can lean on this.

  • Robert Cialdini, Influence (1984, rev. 2021)
  • unity added in Pre-Suasion (2016)

Why it works

These are shortcuts that are usually right, which is why they work and why they can be exploited. Knowing them tells you both what to use and when you are being used.

What to do about it

  • Give first and specifically, before asking — reciprocity is the strongest and most misused of the seven.
  • Get a small public commitment before asking for the large one.
  • Social proof works best when the referents are similar to the person: “people on your street”, not “customers”.
  • Unity is shared identity, not similarity: “we're both from Bihar” beats “we both like cricket”.

Where people go wrong

Manufacturing scarcity or proof you don't have. The levers work once; a caught fake ends the relationship.
