What makes social interactions hard? A computational study of intentions, knowledge, and beliefs.

Summary

Having a social life is engaging and complicated. Still some of its aspects seem harder than others. For instance, telling the truth is much easier than lying. Deception demands the ability to simulate another's reaction in order to determine if a lie will be believable. It is even harder if the goal of the lie is to manipulate. To successfully incept an idea in someone's mind I need to predict the way he will revise his beliefs and knowledge. How hard is it to be a skillful liar and what makes it hard for others to manipulate our beliefs?

The overall aim of this project is to develop a theory that will evaluate factors responsible for the complexity of human reasoning about knowledge and beliefs of others, i.e., epistemic reasoning. Combining, adapting, and enhancing concepts from philosophical logic, cognitive modeling, and computational complexity theory I aim to identify theoretical boundaries in the complexity of reasoning about information flow. I will investigate the borders between easy and difficult epistemic tasks. Finally, I will show how the theoretical findings may be translated into experimental hypotheses. Further on I hope for my theory to be integrated in computational models of cognition with an eye towards education, clinical psychology, and artificial intelligence.
