So,

1) What are the basic science advances that have changed our view of the big questions, and which questions?
2) What are some psychology studies that really show us things we couldn't have known otherwise on the important topics? Treating the abnormal, understanding sensation/perception, and medical therapeutical stuff is a different category.
3) Same as 2, but for the neuroscience, brain imaging type studies

The stuff I've read about falls into three categories: 1) wrong, 2) not really important, 3) laborious and questionable support for something that you will likely come across in the course of a humanities education, which psychologists don't have

But obviously I quit looking into it at a certain point.

We know that science and reason can work well destructively, in pointing out flaws and impossibilities, and this can open peoples eyes. But we are talking here about a direct advance.
