Cover Story: Consumer electronics affect energy use, material extraction, and toxic exposures, and the choice made at End-of-Current-Use (EoCU), i.e., to resell, donate, recycle, or throw away, shapes these outcomes. We surveyed 4000 U.S. users and built a Random Forest model that simulates planned EoCU behavior from 19 attitude and knowledge variables. The model identifies behavioral tipping points, where a small shift in attitude produces a large change in behavior. For example, moving from “Neutral” to “Agree” that reselling is worthwhile increases resale probability by 26%, with little further gain at stronger agreement. Knowing where to recycle shows a similar threshold (+11.6%). This suggests that modest attitude shifts at transition points may be more effective than maximizing positive attitudes when designing interventions. View this paper
