Eglė Butt
Doctoral Topic:
Politeness, severity and risk communication
Area of Interest:
risk perception, judgment and decision making, verbal probability


I am a part-time doctoral student at Kingston University Business School with expected date of completion in 2019. I received a BA (hons) degree in English Language & Communication and Psychology at Kingston University (2008-2011) before joining a doctoral research programme in 2012. My research interests lie in the area of judgment and decision making. Specifically, what factors influence our understanding of probability terms and how to best tailor risk communication in contexts such as criminal litigation and climate change. During my doctoral studies I have worked as a research assisstant (2013-2016), an HPL (2012-2016) and a data analyst (2014-2016). Since 2016 I took on a full-time role as a Planning Officer (Institutional Research) at Kingston University.

Working title: The effect of outcome severity and base rate on the interpretation of verbal probability expressions
Prof Gaëlle Vallée-Tourangeau

Doctoral Details

When making decisions under uncertain conditions with very little information on hand, people do not simply calculate probability. They use subjective knowledge derived from the social context in which the problem is situated. One’s culture of reasoning (e.g., face saving needs) and outcome properties (e.g., outcome severity and base rate) were shown to influence decisions under risk and uncertainty (e.g., communicating the likelihood of a medical condition). In 5 experimental studies, using a regression based mediated moderation approach, my research investigates how people make use of outcome properties to predict legal outcomes and environmental risks, and how face saving measures shape this prediction. Understanding how people interpret probability terms would aid in a more accurate communication of risk and would improve subsequent decision making.
