New spring collection will be coming soon! No human is alike, but we live in the same environment and train our brains together. I believe this creates certain shared structures which can be analysed and understood, at least on a sufficiently useful superficial level. I think anyone who practices a trade a lot will begin to formalise the relevant structures, many of them subconsciously. A musician becomes aware of the structures of a song. A doctor might spot health problems based on very subtle common hints.
