@ChristophMolnar @nntaleb Great cautionary tale. But this is not a satisfying answer. You computed this probability *with* the assumption you suggest one should question. The probability of any sequence of 99, including 50 heads/49 tails, is this small.

@L0RINC @svpino The last sentence is in fact incorrect. We don't know for sure that the doctor can't be male. That's again just a memoized sentence.

4/ E.g. when making coffee, we should place the moka pot on the hob if 1) coffee is ground, 2) the pot is filled and 3) the hob is on; but it doesn't depend on whether we've aired out the kitchen. How do humans carve out such dependence patterns from sequences of actions?

6/ We used a Bayesian sequence model, based on a hierarchy of chunks, to track our participants' skill formation online. The model seamlessly combines predictive information from shorter and longer chunks, weighing them proportionally to their predictive power.

7/ By the way, the model is generally applicable to capture variable-order dependencies in sequence data, for instance, language, bird songs, motor behavior, and more. Feel free to try it out:

To capture action sequences of arbitrary complexity, we use a Bayesian action chunking mechanism which finds statistically reliable structure at different scales. This gives rise to shorter or longer routines that can be embedded into a Monte-Carlo tree search planner.
