This document discusses the relationship between science, politics, and pseudoscience. It examines different ways of categorizing scientific disciplines and proposes a new categorization called "post-normal science" to describe fields with high uncertainty and stakes, like climate change. It also discusses three case studies - the Superconducting Super Collider, the Yucca Mountain nuclear waste repository, and global climate change - to illustrate different types of scientific endeavors based on their levels of uncertainty and decision stakes. Throughout, it emphasizes the importance of understanding how scientific knowledge interacts with political contexts and authorities.
