Research project: A sense of truth: Illuminating illusory truth effects

Abstract

21st Century life in the developed world entails an inexorable bombardment of information. From the trivial to the lifesaving, this information shapes thinking and behaviour. But at our fingertips there are untruths as well as truths. How do we decide what is true and what is not? The sheer volume of information we consume encourages frequent, rapid veracity judgements rather than fully deliberative processing. In the absence of objective knowledge about an unfamiliar topic, the perceived truth of a statement can be influenced by superficial characteristics rather than the probative, informational content of the statement. That is, signals that provide no intrinsic information about truth are used to inform truth judgements.

Two such non-probative cues are repetition and concrete language. Repeated statements (the illusory truth effect) and concretely written statements (the linguistic concreteness effect) are believed more than new or abstract statements. My thesis investigates the moderators of these two truth effects with a view to understanding how they can be applied to support facts with better communication and arguments.

Biography

I am an experimental psychologist interested in the heuristics we use to make every day judgements and decisions. In my substantive research, I investigate how people use non-probative cues to make truth judgements in the absence of information or knowledge. I'm also interested in psychological methods, meta-science and philosophy of science. I am passionate about improving the reliability of scientific research through using and promoting open science practices including pre-registration and open data. I am an Ambassador for the Center for Open Science, a community committee member for Open Thesis.

Prior to beginning my current academic career, I spent 13 years in business, product development and design within the fashion industry.
