Wearable Reasoner: Towards Enhanced Human Rationality through a Wearable AI Assistant
We present "Wearable Reasoner," a proof-of-concept wearable system capable of analyzing if an argument is stated with supporting evidence or not to prompt people to question and reflect on the justification of their own beliefs and the arguments of others.
In an experimental study, we explored the impact of argumentation mining and explainability of the AI feedback on the user through a verbal statement evaluation task. The results demonstrate that the device with explainable feedback is effective in enhancing rationality by helping users differentiate between statements supported by evidence and those without. When assisted by an AI system with explainable feedback, users significantly consider claims given with reasons or evidence more reasonable than those without. Qualitative interviews demonstrate users' internal processes of reflection and integration of the new information in their judgment and decision making, stating that they were happy to have a second opinion present, and emphasizing the improved evaluation of presented arguments.
