Through lessons, reflections, and interactive exercises, the app introduces common cognitive biases, logical fallacies, and reasoning traps, and shows how to recognize them in everyday life. Whether youβre interested in psychology, curious about philosophy, or simply want to make more objective decisions, Unbiased offers a quiet place to sharpen your thinking.
