The document discusses the societal impact and cost-benefit analysis of heritage science. It notes the importance of bringing data to inform decisions rather than just relying on narratives. When comparing costs and benefits, only government considers any benefit, however small, to be worth any cost, however large; most people and businesses weigh benefits against costs. The value of coordination, efficiency, quality, and harmonization in heritage science is discussed. Recommendations include planning with ambition but assessing with caution, bringing quantitative data when possible, and assessing and managing risks.
