Practical posts give direct, actionable advice on how to achieve goals and generally succeed. The art of rationality would be useless if it did not connect to the real world; we must take our ideas and abstractions and collide them with reality. Many places on the internet will give you advice; here, we value survey data, literature reviews, self-blinded trials, quantitative estimates, and theoretical models that aim to explain the phenomena.
Material that is directly about how to think better can be found at Rationality.
