Theory Briefing
- Johns Hopkins researchers have produced new findings that directly challenge the dominant stimulus-response framework underlying habit science for over 100 years.
- Classical conditioning theory holds that habits form through repeated cue-reward loops, but the new study's data suggests the brain's habit circuitry is more flexible than that.
- If the old model is wrong, decades of behaviorist-based interventions — from addiction therapy to productivity coaching — may need a fundamental rethink.
