Professor of Computational Social Science
Deputy Director of the MBA Programme
Academic Director of the Psychometrics Centre
BSc, MSc, PhD (University of Nottingham)
My research interests include psychometrics, psychology, decision-making, and social networks. I use big data to understand psychology, and I also do consultancy on the topics of psychometrics, and people analytics. My research has been cited by many governments’ national data protection regulators worldwide.
I’m a member of the Organisational Behaviour subject group at Cambridge Judge Business School, which aspires to promote our understanding of behaviour within organisations and translate our scientific research into practical applications.
Professional experience
David’s research uses big data to understand psychology. He published papers showing using social media data from millions of consenting individuals to show that the computer can predict a user’s personality as accurately as their spouse can. Follow-up research found that personalising an advert to the recipient’s psychology is more effective than generic ads.
This research has important public policy implications. Do consumers prefer their online experiences to be customised? How should consumers’ data be used to target them? Should regulators step in, and if so how?
David has spoken at workshops organised by the EU Data Protection Supervisor, by the European Parliament’s Science and Technology Options Assessment Panel, to UK government regulators, and to the Bank of England. His research has also been cited by many governments’ national data protection regulators worldwide.
David has also published research using various big data sources such as credit card data and textual data to show that spending money on products and services that match one’s personality leads to greater life satisfaction, that people tend to date others who have a similar personality, and that people who swear seem to be more honest.
David does consultancy on the topics of psychometrics, people analytics, and big data. He has worked on projects with companies including Amazon Payments, Barclays, Hilton Hotels, RBS, Shell, and Ubisoft.

Cambridge study highlights how social media turns values into negative traits
David Stillwell, Professor of Computational Social Science and Director of the Psychometrics Centre at Cambridge Judge Business School, speaks about the consequences of privileging hostile or negative content on social media.
“Even words connected to politics that seem to represent positive values – such as justice, democracy and equality – can actually result in negative sentiment because of the way those words are often used in tweets,” says David.

The arguments for and against swearing
A study co-authored by David Stillwell, Professor of Computational Social Science and Academic Director of the Psychometrics Centre at Cambridge Judge Business School, is mentioned in an article about swearing, after BBC was forced to issue a swift apology for broadcasting a swear word during its coverage of the Oxford-Cambridge Boat Race.
“Swearing is often inappropriate but it can also be evidence that someone is telling you their honest opinion. Just as they aren’t filtering their language to be more palatable, they’re also not filtering their views.” David said.
