They’re called universities. My PhD adviser taught me to think rationally and caught many of the errors in my thinking, including those caused by biases. This eventually allowed me to catch many of my own errors.
No, it wasn’t perfect. It was limited to one academic area and was not explicitly aimed at teaching rationality and overcoming biases. (Then again, martial-arts senseis do not teach their skills “explicitly”, but by repetition and training.) Moreover, gaining subject-matter expertise took as much of the effort as learning rational thinking processes. But a PhD in a rigorous field from a good university is as close as you’ll find to a “color belt” (dare I say “black belt”?) in rationality.
