I spend way too much time thinking about how to think. It as actually something that has a word for it called metacognition.
Metacognition refers to one’s knowledge concerning one's own cognitive processes and products or anything related to them, e.g., the learning-relevant properties of information or data. For example, I am engaging in metacognition if I notice that I am having more trouble learning A than B; [or] if it strikes me that I should double check C before accepting it as fact.—J. H. Flavell (1976, p. 232).
My wife says it much easier, “there you go thinking about thinking."
Here is something to get you thinking. Our memory is fragile.
The above is from this Ted Talk by Elizabeth Loftus on The Fiction of Memory.
Why go through all this? Because if you can design systems that account for people’s tendency to not be able to know when they are telling the fiction of their memory, you can see things others can’t.
