When bridging an inferential distance, see where you are now, and then see where the experts are. That should help uncover the ignorance of your ignorance and make it possible for you to move towards the experts in knowledge-space. If you don't know where the experts are in knowledge-space, then you can easily stumble along in the dark until you end up at bullshit.

The next course of action is to actually move towards the experts in knowledge-space. Textbooks, expert blogs, wikipedia, classes, and so on are all viable methods for that.

But besides understanding the area well, I think you also want to understand or mentally model autists. In which case, you should become familiar with actual autists (through e.g. documentaries, books, and personal communication).
