Hi, I'm Martijn
I am a behavioral scientist working at the Maastricht University School of Business and Economics. I am driven by the curiosity to find out what people (cognitively) do, far beyond what they think they do.
My research varies across multiple topics, with the same recurring theme: investigating the inaccuracy of human judgment, factors that unconsciously influence resulting decisions, and the unawareness of that influence. I use lab and online experiments to explore the behavioral side of many real-life, relevant, economic and societal problems.
Currently, I am moving towards a data-driven exploration of behavior, where I contrast reported or intended with actual behavior.
