Evolution. Vaccines. Global Warming. Regardless of one's choice of news media, it is nearly impossible to navigate today's information-heavy world without coming across stories on evolution, vaccines, and global warming. Each of these topics is the subject of various conspiracy theories and misinformation campaigns. How do we make sense of what we hear on the news when so much information comes from unvetted and non-neutral sources, such as the Internet and the media? This course is a non-technical introduction to these three critical matters in modern science. We will examine what scientists know, how they know what they know, how certain they are, and why there is such a disconnect between scientific understanding and the public's perception of the science.
