I wonder if the hole left by failing interventions is actually an opportunity for a different type of intervention.

The whole point of BE-based intervention is that humans have a limited amount of reasoning power to put towards a given decision and can’t always choose rationally, so the nudge is amplifying a heuristic to make it easier to choose something.

The restrictions of human cognition don’t go away - a failing tactic might simply mean opportunity for a new tactic.

We’ve seen this example with things like “fair pricing model” - this is a heuristic shortcut for trustworthiness. You aren’t trying to nudge me? Great!

Certainly new interventions will surface in response.
