motivating social distancing during the covid 19 pandemic an Online Experiment
Social Science & Medicine, 2020Co-Authors: Pete Lunn, Shane Timmons, Cameron Belton, Martina Barjakova, Hannah Julienne, Ciaran LavinAbstract:Abstract Rationale Maintaining social distance during the COVID-19 pandemic can save lives. We therefore set out to test communication strategies to promote social distancing. Objective We aimed to test two novel public health messages against a control message. The first was designed to exploit the “identifiable victim” effect by highlighting the risk of transmission to identifiable vulnerable persons. The second sought to counteract intuitive underestimation of exponential transmission. Method In total, 500 Irish adults undertook a pre-registered, Online Experiment. They were randomly assigned to a control group or one of two treatment groups. The control group viewed a current poster that encouraged a 2-m separation between people. The two treatment groups saw posters of similar design, but with narrative messages describing how an individual had infected a specific vulnerable person or multiple other people. Later questions measured intentions to undertake three specific types of social interaction over the coming days and the stated acceptability of three other types of social interaction. Pilot work had identified these six behaviors as “marginal” – people were unsure whether they were advisable. Results Participants in the treatment conditions were more cautious about undertaking the behaviors and less accepting of them. This positive effect occurred despite participants rating the treatment posters as likely to be less effective and memorable than the control poster. Conclusions Messages that invoke thoughts of infecting vulnerable people or large numbers of people can motivate social distancing and, hence, help to limit the spread of COVID-19. Stated public evaluations (obtained via focus groups or surveys) may underestimate the actual effectiveness of such emotional messages.

beyond persistent excitation Online Experiment design for data driven modeling and control
IEEE Control Systems Letters, 2022Co-Authors: Henk J Van WaardeAbstract:This letter presents a new Experiment design method for data-driven modeling and control. The idea is to select inputs Online (using past input/output data), leading to desirable rank properties of data Hankel matrices. In comparison to the classical persistency of excitation condition, this Online approach requires less data samples and is even shown to be completely sample efficient.

all by myself testing descriptive social norm nudges to increase flood preparedness among homeowners
Social Science Research Network, 2020Co-Authors: Jantsje M Mol, W Wouter J Botzen, Julia Blasch, Elissa Kranzler, Howard KunreutherAbstract:Nudges based on social norms (norm-nudges) can be compelling behavioral interventions compared to traditional interventions such as taxes and regulations, but they do not work in all circumstances. We tested two empirical norm-nudge frames in an Online Experiment on taking measures for flood preparedness with large samples of homeowners (N =1805) in two European countries, to evaluate the possible interactions between norm-nudge effectiveness, individual characteristics and intercultural differences. We contrasted these norm-nudge treatments with a control and norm focusing treatment by asking respondents to express their beliefs about what other respondents would do before making a decision relevant to their own payoff. We find no evidence of a treatment effect, suggesting that our social norm-nudges do not affect flood preparedness in the context of a flood risk investment game.

loss aversion fails to replicate in the coronavirus pandemic evidence from an Online Experiment
Economics Letters, 2021Co-Authors: Michael Sanders, Emma Stockdale, Susannah Hume, Peter JohnAbstract:Loss aversion is a foundational bias and is a natural choice for interventions encouraging compliance during COVID-19. We compare the effectiveness of loss and gain messages and find no difference in the intention to comply with guidance or lockdown beliefs.

loss aversion fails to replicate in the coronavirus pandemic evidence from an Online Experiment
Social Science Research Network, 2020Co-Authors: Michael Sanders, Emma Stockdale, Susannah Hume, Peter JohnAbstract:Loss aversion is one of the foundational phenomena in behavioural economics and behavioural science. It is also one of the most widely replicated in basic science studies, and one which has found a regular use in behavioural public administration. It is therefore a natural choice for interventions aiming to encourage compliance with rules put in place to stem the COVID-19 pandemic. We compare the effectiveness of loss and gain messages in the context of COVID-19 in the UK. We find no differences in intention to comply with guidance, or belief about how long the lockdown should continue, comparing a gain and loss framed message. We suggest reasons why this might be the case, including the heightened emotional valence of the pandemic.
