Across the world, surveys shape decisions made by governments, NGOs, journalists, international organisations, and private firms. They influence public policy, democratic debates, and how inequality is understood.
But surveys rely on a powerful assumption: that respondents are attentive, engaged, and equally willing to express their views.
What if that assumption is wrong?
If you are interested in quantitative methods, political behaviour, and the ethics of measurement, this PhD offers the opportunity to rethink how we evaluate public opinion data.
The Project
You will develop advanced probabilistic and latent modelling approaches to capture variation in respondent engagement and response quality. Rather than relying on blunt exclusion rules (such as response-time cut-offs), the project treats attentiveness as a spectrum — enabling more precise and inclusive assessments of data quality.
There is scope to examine:
- How survey mode and environment shape engagement
- Whether social desirability and framing effects vary across groups
- How data-quality decisions affect representation and inequality
You will benchmark innovative modelling strategies against conventional rule-based approaches, assessing their implications for validity and democratic representation.
Data and Training
You will work with the British Election Study, Afrobarometer, and the UK Youth Poll, enabling comparative analysis across political, cultural, and generational contexts.
Supervised by Professors Thomas J. Scotto and Robert Mattes, and Dr Joe Greenwood-Hau, you will receive advanced training in latent modelling and applied survey research, with clear pathways to peer-reviewed publication and engagement with survey practitioners.
This project does not simply ask who to exclude from surveys.
It asks how to measure public opinion more accurately — and more fairly.
