I am considering trying this, and I'm wondering if anyone on LW has tried this or something similar. This seems like it could work, but it also seems like it could be hokum. A simple search for "how to develop a photographic memory" returns any number of methods. If this works with the success rate that they imply, this seems like tremendously low hanging fruit.
This is generally an excellent strategy.
As a skeptical learner, I use this strategy in college to decide which science/engineering professors I can trust. For a given professor it lets me know if I should look up the evidence for everything they teach me, or just believe it and move on.
I want to be skeptical, but I don't have time to learn everything in my field from raw empirical evidence, because it's too much material. This let's me identify the subjects most likely to be poorly supported, and investigate them for myself in detail.
