Study registration «The Foundations of Successful Financial Decision Making”

Investment decisions are complex, and one often knows only later whether a decision was a good one. With your participation you will help us to better understand the decision-making processes for financial investments and to identify the most important personality traits of successful investors. Our study examines the decision-making processes using the latest neuroscientific and psychological methods. Our goal is to analyze the role of the trader personality in investment decisions. We also determine to what extent neural predispositions have an influence on it. As the study progresses, you will receive individualized feedback that could help you make better decisions in the future.

Participation is open to all individuals between 18 and 75 years of age. Please note that due to data analysis requirements, we can only consider participants who have an account with Swissquote. The study is conducted in English and German.
