Scientific politics is a way of making decisions about things like laws, public health, and the environment based on science instead of opinion. That means scientists have looked closely at the facts and done research to learn the safest and most reliable way of doing something. For example, if a company wants to build a new factory and scientists researching the project find out that the factory would produce too much pollution, then the scientific politics would be to not let the company build the factory, since the pollution would be dangerous to the environment and people living nearby.
