This well-researched book by teaching librarian Swanson is aimed at educators who seek to recognize principles from neuroscience and psychology regarding how the mind processes information and the role of emotions in information processing. Swanson effectively argues that emotions contribute to decisions produced by unconscious processing and drive much of human thinking. Emotion can overshadow both conscious reasoning and the examination of evidence. Especially interesting is Swanson's focus on metacognition and reflection, as this invites readers to make judgements about their own beliefs. Recognizing the feeling of knowing may help people better identify confirmation bias and perhaps other mechanisms that reinforce existing beliefs during the information-seeking process. Swanson, who served on the Association of College and Research Libraries' task force responsible for issuing the Framework for Information Literacy for Higher Education, proposes an additional frame titled "Knowledge as a Feeling" to address how the mind works through challenging ideas during the research process. Swanson also explores how the feeling of knowing is highly situational and social, dependent on people's relationships within social groups and their life experiences, worldview, and culture. This book is a good contribution to the literature supporting information literacy instruction by educators. Recommended. Graduate students, faculty, and professionals.
