On Expertise

Watch “PSU Press Presents: Communication in the Disinformation Age,” a virtual author event hosted by the Press on April 8th, 2022 with Ashley Rose Mehlenbacher, Seong Jae Min, Billie Murray, and moderator Mary E. Stuckey:

There is a deep distrust of experts in America today. Influenced by populist politics, many question or downright ignore the recommendations of scientists, scholars, and others with specialized training. It appears that expertise, a critical component of democratic life, no longer appeals to wide swaths of the body politic.

On Expertise is a robust defense of the expert class. Ashley Rose Mehlenbacher examines modern and ancient theories of expertise through the lens of rhetoric and interviews some forty professionals, revealing how they understand their own expertise and how they came to be known as “experts.” She shows that expertise requires not only knowledge and skill but also, crucially, an acknowledgment by others—both specialists and laypeople—that one is a credible authority. At its heart, expertise is a rhetorical construct, and to be persuasive, experts must have the ability to apply their knowledge and skills rightly—in the right way, at the right time, to achieve the right end. Ultimately, Mehlenbacher argues that experts apply their technical knowledge effectively and win others’ trust through acting prudently and cultivating goodwill.

Timely, practical, and sophisticated, On Expertise provides vital scaffolding for our understanding of expertise and its real-world application. This book is essential for beginning the work of rehabilitating the expert class amid a politics of extreme populism and anti-intellectualism.

“On Expertise is an important and well-executed project, combining theoretical discussions with qualitative data collections such as surveys and interviews to answer the question of whether we can change the public’s attitude toward expertise and its ability to participate in discourses of expertise for the better. With cautious optimism, it enters into a crisis with a long and sordid history of a public's deep distrust and skepticism.”—E. Johanna Hartelius, author of The Gifting Logos: Expertise in the Digital Commons

“Mehlenbacher's expansive understanding of the conceptualization, application, and reception of expertise is much needed—even essential—in the present cultural moment.”—L. H. Taylor Jr., Choice
