The Nobel committees for Physics, Chemistry, and Physiology or Medicine do a great job on the whole. Major advances are identified annually, and outlined for anyone to see.
Assessment is done the only sensible way – by inviting nominations as the basis for a decision on importance, this being made by a small group of distinguished scientists actively involved in each subject. No metrics, proxies, nor impact statements. No publication counts, journal impact factors, grant income. Compare with UK REF, research “performance management”, and nonsensical league tables.
Dissemination takes the form of the motivation and background to the awards. These are are models for increased public understanding of new discoveries and their significance.
