Experiments and societal challenges
The randomised controlled trial is seen as the gold standard within the social sciences. I do not disagree. I love well-executed experiments with strong causal identification. If two studies, one experimental and one non-experimental, differ in their conclusions, there is no doubt which study I, all else equal, will side with. Most importantly, I often […]

I did not find the glossary easy to skim through so I decided to download the glossary from GitHub and make my own table with the 261 entries. Here it is: Title […]
How effective is nudging? #2
In a new study, Mertens et al. (2022) examine the effectiveness of nudging. Specifically, they conduct a meta-analysis of 455 effect sizes from 214 publications. Here is the key finding presented in the abstract: “Our results show that choice architecture interventions overall promote behavior change with a small to medium effect size of Cohen’s d […]
Datavisualisering: Se & Hør-pigen
Før du læser videre: Den eneste model du kommer til at se i dette indlæg, er en multipel lineær regressionsmodel. Forleden fandt jeg en oversigt med Se & Hør-pigen fra 1998 til 2022 (det hedder mærkværdigt nok ikke Se & Hør-kvinden til trods for at det hedder Se & Hør-manden). Oversigten er tilgængelig som en […]
