Think Before You Like edit

In a review in Skeptical Inquirer magazine, researcher Ben Radford writes that Harrison examines social media offering "practical advice on media literacy and cyber self-defense". Radford states that Chapter 2 might be the most relevant to skeptics trying to "understand the psychological and social consequences of social media". Think Before You Like was published in 2017 before information about how the power of social media was used in the US Presidential elections. Yet, according to Radford, "Harrison's book will only become more timely in the coming years".^[12]

At Least Know This edit

Reviewed in the Spring 2019 issue of Skeptical Inquirer by Russ Dobler, who writes that At Least Know This is a primer for the layperson who wants to understand what we know, not necessarily how we know it. Dobler calls this “a Herculean organizational effort” that “excels”. Harrison brings his skills as a journalist as well as his degrees in history and anthropology to discuss weighty topics “spanning all of time and space”. It almost “feels a bit like an attempt at a twenty-first century version of Cosmos” yet, some “science purists who prioritize methodology over trivia” may not agree. Dobler writes: “one step at a time. Bring the wonder, and maybe the rigor will follow”.^[11]
