Keep It Simple: Why Theory-Derived Messages Do Not Outperform a Neutral Appeal for Tourist Water Saving
Two pre-registered survey experiments with Australian and UK tourists test five theory-informed water-saving messages in a farm tourism context, finding that none outperform a simple neutral appeal. The study extends the standard pre-testing protocol for behaviour change interventions by adding scrutiny of neutral control conditions and cross-cultural validation — two steps that materially change which interventions look promising before costly field deployment. Humour emerges as the one approach with a genuine supplementary advantage. Cultural differences between Australian and UK participants serve as a practical caution for international properties.
