About
55 cognitive biases styled as a social feed. Each bias is a post: image, simple real-life example, more examples as comments, space for your own note, and a Wikipedia link for the details.
The goal is educational. Scroll through a feed instead of a brainless reel, each post teaches something about the traps of your mind.
Content source: Wikipedia (list of cognitive biases). Images: AI in editorial-flat style, each unique. View counts: real, fetched weekly from the Wikipedia API.
You can subscribe to the newsletter and receive one bias per day for 55 days at 8:00 AM.
