Find out, for any named finding, whether the field still believes it, before you spend a term building on it.
Find out what your textbook simplified, softened, or left out entirely, and why, which is usually more informative than the simplification.
Find out which documented psychology myths you're carrying, the ones that survive a degree, not just a childhood.
