Mental models, decoded from real events
See the hidden forces behind the events that shaped the world — and build a mind that spots them everywhere.
Interleaving works not because it improves learning of any single topic, but because it forces the brain to repeatedly practice the act of selecting the right strategy—the meta-skill that blocked practice never develops. In blocked practice, the problem type is known before you start, so strategy selection is bypassed entirely. Interleaving ensures that 'what kind of problem is this?' is practiced as intensively as the solution procedures themselves, which is exactly what real-world performance demands.
