Prostir.info is a field guide to the persuasion tactics, dark patterns, and pricing tricks companies use every day — and how to spot them.
The Mission
Every day, marketers and product designers use well-researched psychological tactics to influence what you buy, how you decide, and what you click. These techniques come from academic research traditions — behavioral economics, social psychology, advertising science, and UX design — and they’ve been refined over decades.
This site documents these tactics in plain language, with real-world examples and the research lineage behind each one. The goal is to help you recognize when you’re being nudged, manipulated, or otherwise influenced — so you can make clearer, more autonomous decisions.
The Approach
Each tactic on this site is:
- Named and defined — Clear explanation of what the tactic is and how it works
- Traced to research — Linked to the academic tradition that discovered or named it
- Shown in practice — Real-world examples from marketing, UX, and product design
