The domains Klein studied, in which instinctive pattern recognition worked powerfully, are what psychologist Robin Hogarth termed "kind" learning environments. Patterns repeat over and over and over and feedback is extremely accurate and usually very rapid.
In wicked domains, the rules of the game are often unclear or incomplete. There may or may not be repetitive patterns, and they might not be obvious, and feedback is often delayed, inaccurate, or both.
