New open-access paper with @SanchayanBanerj in Behavior Research Methods RCTs tell us what works. BriDGE helps show why and how: DAGs + causal discovery + GAMs + mediation in one workflow. R package included 👇 link.springer.com/article/10.3...
BriDGE the gap: Improving behavioral research by integrating DAGs and GAMs into experiments - Behavior Research Methods
Understanding the mechanisms through which behavioral interventions work remains a critical challenge in behavioral science. While randomized controlled trials (RCTs) provide reliable evidence for int...

Where quantum and quantum-like methods earn their place in behavioural-trial analysis: three simulation pilots across the RCT pipeline
Behavioural randomized controlled trials (RCTs) are the empirical workhorse of behavioural science, yet quantum computing has reached the field only through opinion-dynamics demonstrations and decisio...

Sorry to miss #IBPPC2026 in Brisbane next week. eVisitor lodged on 25 August, still undecided — no info request, no correspondence, no outcome. Travel's off. I was due to present on i-frame vs s-frame interventions under model misspecification. DM me for the paper. Enjoy Brisbane.

New in JASSS: should behavioural policy target individuals or systems? An ABM finds s-frame seeding is more transformative and cost-efficient — and far more fragile. i-frame nudges win less but degrade gently. Not either/or: a portfolio. www.jasss.org/29/3/1.html

Behavioural interventions do not operate in a social vacuum. In a paper with Alberto Acerbi, we show that interventions can stall or cascade depending on how people learn from others. Behavioural policy must study diffusion—not only individual effects. www.cambridge.org/core/journal...

The Effects of Data Preprocessing Choices on Behavioral RCT Outcomes: A Multiverse Analysis
Seemingly routine data–preprocessing choices can exert outsized influence on the conclusions drawn from randomized controlled trials (RCTs), particularly in behavioral science where data are noisy,...

Adding social learning strategies to understand behavioural interventions using ABM models sparked an engaging discussion at the LSE-Cambridge BPP workshop!
I have developed an R package called multiverseRCT, It lets you: - Apply multiple preprocessing methods - Fit multiple model specifications - Visualise the variation in treatment effects across the multiverse - Quantify the sensitivity of conclusions to analytic decisions 👇 shorturl.at/GFD3M
