An idea that I'm kicking about: intuitive organisational schemas for knowledge.

I've previously observed that it's easier to process and retain facts about places if you know where those places are on a map. Knowing the map gives you an intuitive schema to hang the information on. I am never going to have to navigate to Kiribati or the Pitcairn Islands, but I suspect some part of my brain which handles spatial orientation and navigation is putting in some overtime and helping me remember things about them.

I'm considering making an anki deck of people. Historical scientists, mathematicians and philosophers, and contemporary academic and industrial figures. It could include photos/portraits, their field, their active period, maybe their nationality, and specific theories, ideas or publications they're known for. Much like knowing where Kiribati is on the map gives me a mental "space" to put facts about Kiribati, perhaps having a personal sense of Tooby and Cosmides and Trivers and Dunbar are will give me a similar "space" to put facts about ev-psych.

In principle, this shouldn't be too hard. Without any assistance, most people remember details on hundreds of real-world acquaintances and thousands of celebrities and fictional characters. In practice, I remember struggling with the Monarchs of England deck, with eight Edwards, six Georges, and more Henrys than you can shake a stick at. I ended up solving this by watching films and plays featuring the monarchs in question, but this probably isn't available for my deck of thinkers. None of them feature in the legend of Robin Hood.
