In Jonah Berger’s framework, Social Currency and Triggers work as complementary forces to drive both initial excitement and long-term viral momentum.
1. Motivation vs. Memory
- Social Currency provides the motivation (Why people share): People share remarkable, novel, or exclusive things because it makes them look smart, cool, or in-the-know. Social Currency generates immediate word of mouth right after someone experiences or hears about an idea.
- Triggers provide the memory cue (When people share): Triggers are environmental stimuli—sights, sounds, times of day, or daily habits—that prompt people to think about related ideas. Triggers drive ongoing word of mouth over weeks and months by keeping the idea top of mind.
2. Immediate Buzz vs. Ongoing Momentum
An idea needs both principles to achieve sustained virality:
- High Social Currency without Triggers: A trip to Disney World or a remarkable one-time event creates a massive initial spike of discussion, but because daily life offers few environmental reminders, conversations quickly fade.
- Triggers without Social Currency: Mundane products like Cheerios or Ziploc bags aren't inherently exciting to talk about, but because people encounter them constantly during breakfast or after meals, they generate high ongoing discussion.
- Combining Both: When an idea offers high Social Currency and is tied to a frequent environmental trigger, it gets both an explosive launch and sustained chatter. For example, Barclay Prime's $100 cheesesteak carries immense Social Currency (it's remarkable and outrageous), while the constant presence of cheesesteaks in Philadelphia serves as a frequent trigger to bring it up in conversation.
3. The Rock Band Analogy
Berger compares their partnership to a music group:
Social Currency is the front man or woman—exciting, fun, and getting lots of attention. Triggers are the drummer or bassist—the quiet workhorse laying down the steady rhythm that keeps the song moving.
Ultimately, the core rule connecting the two is: "Social currency gets people talking, but Triggers keep them talking. Top of mind means tip of tongue.".
