Mathematics as a vantage point

The goal of behavioral science research is to explicate human behavior and the structure of society by means of data analysis and mathematical model interpretation. For instance, we tackle questions such as “What mechanisms lead to economic inequality?”; “Why do people feel dissatisfied despite being objectively successful in life?”; “Why do university entrance rates vary depending on the class origin?”; etc.
Some of the students who enter the Faculty of Arts and Letters might assume that those who study humanities have no use for mathematics. Indeed, there exist many phenomena that mathematics cannot describe, but there are also truths that can only be explained with the help of logic and numbers. A whole new world unfolds in front of you when you look at society through the prism of numbers and data. I believe that young university students should bypass the old division between humanities and sciences, and explore the world from many different angles.
