Master your biology. Battle your urges. Never get played. BiasProof is the cognitive bias training app that gamifies mental calibration. In realistic scenarios, you'll spot emotional traps, cognitive errors, and modern scams—building measurable resistance to the thinking pitfalls that derail decisions, relationships, and finances. Manifesto: Defend your mind. The world has changed. It's no longer just about "better decisions"—it's about defense. Your biology works against you: Biases like sunk cost keep you in bad jobs; anchoring fleeces you in deals. Your emotions tempt you: Urgency traps push impulse buys; trends override logic. Bad actors exploit you: AI-powered scams (pig-butchering, voice cloning) target human nature, not stupidity. We have antivirus for devices and locks for doors—but nothing for the software in your head. Until now. The Solution: Train like a martial art. BiasProof turns skepticism into a skill. No dry definitions—we simulate attacks: • Fake "urgent" investments • Tempting viral trends • Pressure-filled demands You make judgments, get instant feedback, and learn counter-moves. Progress through levels, earn streaks, badges, and climb leaderboards. Think of it as Strava for your brain. Why it works: Realistic scenarios from behavioral science Immediate feedback for muscle memory Gamification for daily habit (streaks, challenges, progress tracking) Measurable calibration: Track resistance over time Protect yourself from your own brain—and everyone else's scams.
