About me

Hi! I am a PhD candidate at the Department of Leadership & Organizational Behavior at BI Norwegian Business School. I am also affiliated with Trope Lab at New York University’s Department of Psychology (lab’s website: https://sites.google.com/nyu.edu/tropelab/about?authuser=0). My PhD project seeks to understand how emotions and psychological distance influence decisions involving risk and uncertainty. Methodologically, I primarily use experiments in order to uncover the causal nature of the relationships. I am a big fan of open and reproducible science. Together with a colleague and PhD candidate, we have set up an open science journal club at our department (ReproducibiliTea BI Oslo) that we are organizing together. The goal of our journal club is to raise awareness of open science and reproducibility (see “Projects” for more info).

A Replication of Study 1 in "Differentiating Social and Personal Power" by Lammers, Stoker, and Stapel (2009)

We performed an independent, direct, and better powered (N = 295) replication of Study 1, an experiment (N = 113) by Lammers, Stoker, and Stapel (2009). Lammers and colleagues distinguished between social power (influence over others) and personal power (freedom from the influence of others), and found support for their predictions that the two forms of power produce opposite effects on stereotyping, but parallel effects on behavioral approach. Our results did not replicate the effects on behavioral approach, but partially replicated the effects on stereotyping. Compared to personal power, social power produced less stereotyping, but neither form of power differed significantly from the control condition, and effect sizes were considerably lower than the original estimates. Potential explanations are discussed.
