Technically, simplicity corresponds in a drop in Kolmogorov complexity, which means that, for an observer, the shortest description of the situation is shorter than anticipated.
Simplicity theory makes several quantitative predictions concerning the way atypicality,[7] distance, recency or prominence (places, individuals)[5] influence interestingness.
corresponds to generation or causal complexity, which is the smallest description of all parameters that must be set in the "world" for the situation to exist.
For instance, the typical draw 12-22-27-37-38-42 will appear very simple, even simpler than the consecutive one, to the person who played that combination.
Simplicity theory measures it based on randomness deficiency, or complexity drop.
