Our society is drowning in information, so how do you avoid being fooled by bogus claims? In this class, we will examine two provocative topics (the age of Earth and the universe and climate change) where the data and our underlying beliefs often push us toward contradictory conclusions. We will learn how to study these ideas critically while remaining professional and respectful in our discourse. Our examination of these topics will be informed by the complementary perspectives of the humanities, the social sciences, and the natural sciences. Students will learn the fundamental science and data interpretation skills needed to understand these topics, how to deal with probability and uncertainty in science, how to recognize logical fallacies in arguments, how to critically examine claims, the psychology of belief systems, and how our brains decide what to accept and what to reject when we are forming beliefs.
