How Starbucks uses Psychological Triggers

I like this picture from Tom Pestridge that breaks down physiological triggers Starbucks uses for their different sized.
Here's what he said:
The psychological triggers Starbucks uses...that make people keep coming back.
1. The Decoy Effect
↳ A strategically placed middle option can make the most expensive seem like the best deal.
2. The Von Restorff Effect
↳ Writing your name wrong, makes it stand out and encourages social sharing and free advertising.
3. The Customization Effect
↳ Allowing endless small choices increases attachment and perceived control.
4. Artificial Constraints
↳ Limited-time offerings increase desire and speed up decision-making.
5. Sunk Cost Fallacy
↳ The more effort people invest, the more committed they become.
6. Status Signaling
↳ Creating visible loyalty tiers taps into pride and exclusivity.
7. Endowment Effect
↳ Writing your name on the cup creates a feeling of ownership.
8. Sensory Branding
↳ Smells, sounds, and visuals build emotional memory and comfort.
We like to think we’re all rational buyers.
The truth?

Master these tactics, and you’re not just marketing. You’re creating movements.
