Can behavioral interventions be too salient? Evidence from traffic safety messages
https://www.science.org/doi/abs/10.1126/science.abm3427 Contrary to policy-makers’ expectations, we found that displaying fatality messages increases the number of traffic crashes. Campaign weeks realize a 1.52% increase in crashes within 5 km of DMSs, slightly diminishing to a 1.35% increase over the 10 km after DMSs. We used instrumental variables to recover the effect...
On the value of modesty: How signals of status undermine cooperation
https://psycnet.apa.org/doiLanding?doi=10.1037%2Fpspa0000303 The widespread demand for luxury is best understood by the social advantages of signaling status (i.e., conspicuous consumption; Veblen, 1899). In the present research, we examine the limits of this perspective by studying the implications of status signaling for cooperation. Cooperation is principally about caring for others, which is...
Deep models of superficial face judgments
https://www.pnas.org/doi/full/10.1073/pnas.2115228119 The diversity of human faces and the contexts in which they appear gives rise to an expansive stimulus space over which people infer psychological traits (e.g., trustworthiness or alertness) and other attributes (e.g., age or adiposity). Machine learning methods, in particular deep neural networks, provide expressive feature representations of...
How to measure and mitigate position bias
https://eugeneyan.com/writing/position-bias Position bias happens when higher positioned items are more likely to be seen and thus clicked regardless of their actual relevance. This leads to lesser engagement on lower ranked items. On Google Search, users click on the first position 10x more than the tenth position. Because of position bias,...
Normalizing the use of single-item measures: Validation of the single-item compendium for organizational psychology
https://link.springer.com/article/10.1007/s10869-022-09813-3 The application of single-item measures has the potential to help applied researchers address conceptual, methodological, and empirical challenges. Based on a large-scale evidence-based approach, we empirically examined the degree to which various constructs in the organizational sciences can be reliably and validly assessed with a single item. In study...
Data team structure: embedded or centralised?
https://mikkeldengsoe.substack.com/p/data-team-structure-embedded-or-centralised Should my data team operate centralised or embedded? Some teams naturally tie themselves to being centralised. Data engineers for example benefit from working on shared objectives such as improving data pipelines or tooling. Analysts with domain expertise in credit modelling may tie themselves better to being fully embedded and...
Best vs. Rest explained
https://www.svpg.com/best-vs-rest-explained/ Steve Jobs argues that for most established companies, innovation is simply not at the core of their DNA. He argues that once they have established their business, the focus of the company quickly moves to sales and marketing: “I have my own theory about why the decline happens …...
The end of Big Data
https://benn.substack.com/p/the-end-of-big-data I first heard about Databricks in 2014. It was Silicon Valley hype, manifest. Databricks’ founders were brilliant computer scientists turned reluctant entrepreneurs. They were reinventing big data, which itself was reinventing the entire world. Growth rates were straight up, and overloaded sales reps were leaving their phones off the...
Everything gets a package? Yes, everything gets a package
https://ericmjl.github.io/blog/2022/3/31/everything-gets-a-package-yes-everything-gets-a-package/ But why all the trouble? Isn’t there a ton of overhead that comes from doing software work? You now suddenly have to manage dependencies, start documenting your functions, add tests… you suddenly can’t just store data with code in the repo… I can’t just commit the notebook and be...
The nature of product
https://www.svpg.com/the-nature-of-product/ In this article, I’d like to share how Steve Jobs tried to explain this concept. In 1995, after he had been fired from his own company, and had some time to contemplate what he’d learned, he was interviewed for a PBS Documentary called Triumph of the Nerds. They only...
