Recognize biases. Decide better.
Our brain relies on mental shortcuts to make quick decisions. BiasCheck makes cognitive biases visible in thoughts and situations and helps you reflect more consciously.
I’ve read three articles that confirm my new project idea. I’m now absolutely certain that I’m on the right track.
We tend to select information that meets our expectations. Have you also specifically looked for critical voices or risks?

Typical cognitive biases
Confirmation bias
We tend to seek information that confirms what we already believe.
Hindsight bias
Afterwards, we believe we “knew it all along”.
Anchoring bias
Initial information strongly influences later judgments.
Example of an analysis
“I’ve already invested so much time and money into this project — we just have to see it through.”
Sunk Cost Fallacy
Past investments influence decisions, even though they should not matter for the current situation. Instead of evaluating future benefits, decisions are driven by what has already been invested.
Focus on future outcomes rather than past costs. Ask yourself which option will bring the greatest benefit going forward — regardless of what has already been spent.
