Thinking and deciding are central to our daily lives. The Less Wrong community aims to gain expertise in how human brains think and decide, so that we can do so more successfully.

We use insights from cognitive science, social psychology, probability theory, and decision theory to improve our understanding of how the world works and what we can do to achieve our goals.

Want to know if your doctor's diagnosis is correct? It helps to understand Bayes' Theorem.

Want to make a plan for achieving your goals? It helps to know the ways in which we don't know our own desires.

Want to make the world a better place? It helps to know about the cognitive bias called 'scope insensitivity', and that some charities are more efficient than others.

We discuss and practice these skills on the main blog (www.lesswrong.com), in the discussion area, and in regular meetups around the world.

This group is a real-life instantiation of the online Less Wrong community in and around Ottawa (Canada). Come meet us if you're in the area.
