This is an AMAZING class that I keep recommending to everyone I possibly can. The subject matter is extremely interesting, since it involves you and everyone you will ever meet. The course is taught by a leading expert in human behavioral genetics, which makes it very thorough, accurate, and his passion for the subject really comes through. It is also an excellent course on scientific thinking- how to think systematically, thoroughly, and in a nuanced, detailed way. Again, I highly recommend it. I've taken a lot of classes (both on and off line), and this one was among my all time favorites.
