Third, there is medium evidence on how trust in state-led, planned adaptation measures can hinder or enable individual adaptation . As an enabler, trust in early warnings can mitigate flood risk by incentivising evacuation  and high trust can help overcome uncertainty attached to projected climate impacts and/or adaptation decisions . As a barrier, low trust can disincentivise adaptation, for example willingness to pay for flood insurance  or public support for managed retreat . Paradoxically, high trust in existing adaptation measures can reduce people's perceived need for ongoing adaptation . Adaptation decisions also manifest 'single-action bias', with modest cost-adaptation actions in the present disincentivising further adaptation .
