What this video covers
Hick's law predicts how decision time rises as choice or uncertainty increases; Miller's law concerns immediate-memory capacity. Neither gives a universal limit for the number of menu items.
Drag the count up and watch them part ways: Hick's time climbs in a gentle curve (deciding gets slower, but never impossible), while Miller's memory hits a wall around seven and tips into overload. Same number feeding two quite different limits - which is exactly why people muddle them.
