When cognitive load is high, reduce the complexity…
When cognitive load is high, reduce the complexity of intended behaviors rather than increasing effort, because executive function required for override degrades under the same conditions that activate problematic defaults.
Why This Is a Principle
Derives from Directed Attention as Depletable Resource (executive function draws from finite resource that depletes with use), The prefrontal cortex requires time to override limbic… (prefrontal cortex requires time to override limbic responses), and Under acute stress, the prefrontal cortex degrades… (under stress, prefrontal cortex degrades while subcortical systems remain operational). The principle prescribes strategic simplification: because override capacity declines precisely when most needed, design must compensate by reducing behavioral complexity rather than demanding greater control.
