Knowledge Is Power, Power Is Not Knowledge
Science is built on knowledge, not on power. A scientific idea is accepted because it survives tests, not because of who proposed it.
Yet politics involves science in an inevitable manner. This factor influences important facts e.g., funding and employment of institutions and individuals. These decisions are necessary.
The understanding of knowledge is binary. Either a person understands a topic, or they do not.
A scientific leader should be honest. They do not pretend to know what they do not yet know, and they say "I don't know yet".
