He is a courtesy faculty member in the department of Information Science of the College of Media, Communication and Information, and a Fellow of the Institute of Behavioral Science. Kai is most known for providing a practical solution to Edward Thorndike's (1904) Jingle Fallacy (Larsen and Bong 2016) and for his contributions to the Semantic Theory of Survey Response (STSR), which holds that results of surveys using attitude scales primarily measure the linguistic relationships between survey questions. Kai’s book on Automated Machine Learning is slated for publication by Oxford University Press in 2019.
