I'm not sure how common the practice is, but I do remember once receiving a 2-euro coin in an envelope to complete an Austrian demographic survey. To be fair, I did end up filling out a questionnaire I would have otherwise always ignored.

Hi Stephanie, can I be added too? Thanks!

Very happy with the work we made, and even happier now that it is available to everyone! 🥳

In my recent paper "Belief Bias Identification" I build a theoretical model to separately identify a notable set of belief updating biases. To test this model in the lab, I use this tool to measure belief distributions. What do I find? What biases come out on top? 🤔
