Place decision nudges at the temporal and spatial point of decision rather than before or after, because nudges lose effectiveness when separated from the moment of choice.
Why This Is a Principle
This principle derives from the axiom that behavior requires an initiating signal (Behavior requires an initiating signal to occur at a), that attention is necessary for perception (Attention as Gate to Conscious Perception), and that attentional systems prioritize immediacy (Human attentional systems evolved to prioritize signals with). The principle prescribes timing and placement of interventions to match the decision architecture of human cognition.
