  "summary": "Interleaving is not multitasking with better branding.",
  "kind": "principle",
  "body": "Mix examples that require you to choose among similar methods, categories or diagnoses inside the same learning goal. Keep unrelated workstreams outside the block. The useful difficulty is deciding which rule applies; the useless difficulty is rebuilding context after every switch.",
  "limits": [
    "Interleaving is not always superior. Use blocked practice when a novice still cannot execute the basic method at all."
