It is important and urgent for the planning agencies to systematically survey the effects of investments in science on indicators of broad well-being. The Royal Netherlands Academy of Arts and Sciences states this in a new advisory report on The Value of Science – Observe, Know and Measure [Waarde van Wetenschap – Observeren, weten en meten]. At present, that value is wrongly absent from the planning agencies' models, leading to underinvestment in science.
