Whether in legislatures or executive government, the core of policymaking is setting agendas and collaboratively making informed decisions. The legal profession instills reliance on adversarial process — wherein two sides present arguments to an impartial arbiter. On the other hand, scientists are taught to prioritize quantitative evidence, economists to study incentives and journalists to suppress personal bias. In government, these approaches can shape how politicians gather information, which experts they trust, and what solutions they favor. Diversity helps ensure that policies are based on the strongest evidence possible.
