Brown Behavioral Decision Sciences: how people judge and decide, and how to do it better
Brown has no set core, and most undergraduates sample subjects before choosing one of 80-plus concentrations. Behavioral Decision Sciences is a B.A. concentration the Bulletin describes through descriptive, normative and prescriptive questions about judgement and decision making. This guide makes no claim of a separate application to the concentration.

Read on 1 November 2026 on the Brown Bulletin entry for the Behavioral Decision Sciences concentration and Brown's Open Curriculum, Standardized Tests and international Admission Criteria pages, which describes 2027 entry. The pages carry no entry-year label. Brown's department website, the course descriptions, deadlines and financial aid were not read and are not stated.
The concentration
What the Bulletin says the concentration is
The Bulletin says the study of decision making leads to a Bachelor of Arts and covers descriptive questions about how people, institutions and nations make judgements and decisions, normative questions about what constitutes the best judgements, and prescriptive questions about how decision making can be improved. It draws on psychology, cognitive science, economics, philosophy, computer science and neuroscience. The standard programme is 13 credits. This guide does not list individual courses.
Is it the right concentration?
Behavioral Decision Sciences beside Cognitive Science and Applied Mathematics-Economics
Brown lists these concentrations separately, so the choice is made after admission. Avandy's comparison is general.
This concentration fits if
you want to study judgement and choice across several disciplines.
Cognitive Science fits if
you want the wider study of the mind. Avandy's Brown Cognitive Science guide covers it.
Applied Mathematics-Economics fits if
you want the mathematical side of economics. Avandy's Brown guide covers it.
Admission and testing
A Brown application, an SAT or ACT and A levels or the IB
Brown has returned to requiring SAT or ACT scores for first-year applicants and says there are no minimum scores. International applicants should plan to sit national and international examinations such as the GCE A-levels and the IB and submit predicted or actual scores, with actual scores expected before matriculation. The concentration is not a separate application. This guide states no score.
A decision framework
Three questions before you commit
This is Avandy's own framework, not Brown's.
Do you want to study both how people decide and how they should?
The concentration covers both.
Is an interdisciplinary mix appealing?
It draws on six disciplines.
Can you plan the SAT or ACT with your A levels or IB?
Brown requires one of them for first-year applicants.
