Engineering Intelligence
The specific form of understanding embedded in both designed artifacts and experienced designers — knowledge accumulated through encounter with failure that cannot be fully extracted into specifications, because its essential feature is the judgment to know when the specifications are insufficient.
Petroski used the term engineering intelligence (and related phrases like engineering judgment and engineering wisdom) to name the form of knowledge that distinguishes the engineer from the calculator. The distinction matters because calculation is the domain in which AI excels — where its speed, accuracy, and capacity to evaluate thousands of configurations simultaneously produce results genuinely superior to any human calculator. Engineering intelligence, in contrast, is the exercise of judgment about what to calculate, why to calculate it, and what to do when the calculation is insufficient. It includes calculation but also includes the selection of the problem, the identification of the relevant forces, the assessment of which failure modes are most dangerous, the decision about how much margin to maintain against conditions the calculation does not cover, and the willingness to say not yet when the calculation says a design is feasible but judgment says the understanding is incomplete. AI performs calculation. Engineering
