Passage: The concept of a 'failure mode' in engineering is highly applicable to the 'architecture of cognition.' A failure mode is not a random error, but a systematic way in which a model breaks when its underlying assumptions are violated. In human reasoning, these modes often take the form of 'heuristics'—mental shortcuts that are efficient for daily life but fail under the time pressure and complexity of a professional environment. For the practitioner, knowing when a model breaks is as important as knowing the model itself. A 'disciplined comparison of quantities' requires an awareness of these psychological blind spots. The goal of a practitioner-grade education is to install a 'defense' against these failure modes, replacing intuitive shortcuts with the 'rigor' of the quantitative toolkit. The passage implies that 'heuristics' are:

1. Identical in every respect to the 'failure modes' observed in mechanical engineering systems.
2. Systematic cognitive shortcuts that can be dangerous in professional contexts.
3. The primary and indispensable components of a 'truly integrated' clinical reasoning process.
4. Random, unpredictable errors that occur mainly when a student is poorly prepared.
