Personally when I am looking at something interesting that I want to learn from, I always ask: "What is the difference that make the difference?" These are my general observations: When you do not understand what the important variables are, most often than not, you end up clueless. Humans are not good with too much complexity. When too many variables are playing a role, it is usually not clear what dominates. Being a generalist helps understanding. To figure out what is going on, a generalist mindset helps because you can find clues from other domains. Over generalization is the root of all evils. People usually dramatically fail when they think the situation is the same of one they observed in the past but it is in reality VERY different. This happens because they are looking at variables they observed in the past situation that are similar. But they are not seeing or underestimate other variables that dominate the new situation. In general, even when you think you got it, it is useful to test a few times (assuming you can) to find out, if you really got it right.
