influence-psychology

Layer multiple influence principles: add specific social proof numbers, authority signals like credentials or client logos, and a reciprocity-framed call to action such as a free trial. Score each element against the principles and fix the weakest ones first.

The seven principles are reciprocity, commitment and consistency, social proof, authority, liking, scarcity, and unity. Each describes a mental shortcut people use when deciding, and each has specific product and copywriting applications.

Use only real constraints: actual inventory counts, genuine deadlines, and legitimate capacity limits. Never use fake countdown timers, resetting offers, or fabricated stock levels, since discovered fake scarcity destroys trust and can trigger regulatory action.

Persuasion is truthful, benefits the user, and preserves free choice; manipulation distorts information or undermines autonomy. Apply the transparency test: if the tactic would still work when the user knows exactly what you are doing, it is persuasion.

Design onboarding as a commitment ladder: start with a trivial ask like an identity question, then a stated goal, then a small action, then a public or written commitment. Each small yes makes the next step feel consistent with the user's prior choices.

Avoid social proof when you lack real numbers or testimonials, since fabricated proof destroys trust when discovered. Also avoid negative social proof like highlighting how many people fail to act, which backfires by normalizing the unwanted behavior.
