Abstract
Chatbots are becoming omnipresent in our daily lives. Despite rapid improvements in natural language processing in the last years, the technology behind chatbots is still not completely mature, and chatbots still make a lot of mistakes during their interactions with users. Since it is not possible to completely prevent mistakes due to technological constraints, this article aims to investigate whether a human-like communication style can reduce the negative impact of chatbots? mistakes on users. Taking a combination of the Technology Acceptance Model and the concepts of Perceived Enjoyment and Social Presence as a theoretical basis, we conducted an online experiment in which participants interacted with a chatbot and completed a survey afterwards. We found that chatbot mistakes have a negative effect on users? perceptions of Ease of Use, Usefulness, Enjoyment, and Social Presence. Human-like communication was found to be effective in reducing the negative impact of mistakes on Perceived Enjoyment. Theoretical and practical implications are discussed.
