I developed the BDS concentration in 2017 in response to a demand from students. Several faculty in my department (Cognitive, Linguistic, & Psychological Sciences at Brown University) were getting regular requests from undergraduates to do independent concentrations in topics related to decision making (the psychology of decision making, questions of rationality and epistemology, political decision making, etc.). I'd been teaching a course called Making Decisions--a general introduction to the psychology of decision making, utility theory, and related topics--for many years. So I leveraged the skills and knowledge I had developed to create a quasi-independent concentration. Students develop their own specialization by choosing three advanced electives and do research on the topic, and also choose from a set of required courses.
It turns out that I struck a vein of student interest. BDS started in 2018 and it rapidly became one of the larger concentrations in the department.
If you want to know more about BDS, here's a webpage with a more complete description including the names of faculty affiliated with BDS. They come from my department, Economics, Political Science, Computer Science, Sociology, Philosophy, Neuroscience, and Engineering..
