FOMO (Fear of Missing Out)

The anxiety that others are enjoying rewarding experiences one is absent from; in marketing, content and offers are framed so the audience feels they'll miss a valuable or social opportunity if they don't act.

ref's call

Effective for events, DTC drops, and community-driven brands on social, especially with Gen Z and millennial audiences. Penalized when it manufactures anxiety with no real substance behind the moment. Best for: awareness and engagement for experiential and community plays.

Guerrilla Marketing

An unconventional, low-budget approach that relies on creativity, surprise, and high-impact placement to earn outsized attention and word-of-mouth instead of paid media weight.

ref's call

Punches well above its budget for challenger consumer and experiential brands, especially in urban markets and launch moments. Throws a flag in regulated or B2B contexts where surprise can read as unprofessional. Best for: challenger consumer brands running awareness and launch plays.

Loss Aversion

The behavioral-economics finding (Kahneman & Tversky) that people feel a loss about twice as strongly as an equivalent gain — so framing offers around what's forfeited by not acting can outperform gain-framed messaging.

ref's call

A potent framing lever in retention, subscriptions, finance, and SaaS where there's something to keep or forfeit. Use sparingly and honestly — overused, fear framing reads manipulative. Best for: retention and renewal use cases.

Scarcity & Urgency

Tactics that raise perceived value and prompt action by signaling limited supply (scarcity) or limited time (urgency), drawing on loss aversion and the fear of missing the window.

ref's call

Strong for nudging decisions in retail, e-commerce, events, and DTC — but draws a flag fast when the scarcity is fake (resetting timers, perpetual "last chance"), which erodes trust. Best for: decision-stage conversion backed by real constraints.

Social Proof

The tendency to look to others' actions and opinions to guide our own — so showing that others trust, buy, or endorse something makes new audiences more likely to follow (Cialdini's principle of social proof).

ref's call

A reliable, high-leverage play across nearly every industry, strongest in e-commerce, SaaS, and services where trust drives conversion. Flagged only when the proof is thin or fabricated — hollow numbers backfire. Best for: conversion-stage, trust-sensitive purchases.
