01
Name the idea before the field
Choose a word that appears in several places: intelligence, uncertainty, adaptation, or evidence. Write down what you currently think it means. A clear starting definition makes it easier to notice when another subject uses the same word differently.
02
Compare the kind of evidence
A computational model, a biological observation, and a social explanation answer different kinds of questions. As you read, separate a measured result from an interpretation and a useful analogy. Ask what would have to be true for the explanation to hold.
03
Make a connection you can explain
Write three sentences: what the two subjects share, where the comparison stops working, and what you would like to investigate next. A careful connection leaves room for differences. Keep the question with the next book you choose.
