Behavioural Data in Credibility Assessment: Case Study of Kaja Godek’s Explanatory Statement of Anti-LGBT Law

Abstract

The paper explores the application of behavioural data analysis in the credibility assessment of a speaker. It presents how researchers investigate non-verbal communication, expressions of emotions or indicators of arousal to evaluate congruency using audiovisual material. Furthermore, the case study of Polish political activist Kaja Godek’s explanatory statement of an anti-LGBT bill on October 28, 2021, suggests possible ways, in which the automated system FaceReader (and Facial Action Coding System as its theoretical background) may enrich methods of social science. As a result, it offers an example of an innovative approach towards political communication and the credibility of an argument.
