This is a thread to connect rationalists who are learning the same thing, so they can cooperate.
The "learning" doesn't necessarily mean "I am reading a textbook / learning an online course right now". It can be something you are interested in long-term, and still want to learn more.
Rules:
Top-level comments contain only the topic to learn. (Plus one comment for "meta" debate.) Only one topic per comment, for easier search. Try to find a reasonable level of specificity: too narrow topic means less people; too wide topic means more people who actually are interested in something different than you are.
Use the second-level comments if you are learning that topic. (Or if you are going to learn it now, not merely in the far future.) Technically, "me too" is okay in this thread, but providing more info is probably more useful. For example: What are you focusing on? What learning materials you use? What is your goal?
Third- and deeper-level comments, that's debate as usual.
University courses != helpful. Textbooks, on the other hand, are the fastest way of inputting knowledge into your head.
If you're interested in heuristics and biases, maybe try Heuristics and Biases.
Consider fishing for unknown unknowns, ie. "things I didn't even know existed to study but, having become aware that they exist, believe I really benefit from learning." I'd start with the list of best textbooks. From there, fish through OCW's list of psych courses (these typically come with a textbook recommendation, and MIT tends to use good textbooks). This should keep you busy for a while.
Personal recommendations: I've taken a psychopharmacology course which, while I didn't find the nootropic recommendations I was looking for, has been tons of help in other places in my life, particularly at the doctor's (much lower inferential distance!) and being able to think intelligently about drugs (can't recommend a good textbook, though). I have a personal interest in learning and found Make It Stick helpful, although a bit filler-heavy. The Brain That Change Itself is a wonderful read about neuroplasticity. The Seven Sins of Memory is good.
Thanks, these look really useful. I will definitely have a look at them.
