Professor David Brown explains how simple strategies can guide better decisions even when information is incomplete

New job postings appear daily. Real estate markets update constantly with fresh listings. In an environment where alternatives continuously multiply and options can seem endless, the hardest decision is knowing when to stop searching and commit.

In this episode, David Brown, the Snow Family Business Professor of Decision Sciences at Duke University’s Fuqua School of Business, discusses how people and organizations can make better decisions when information is scarce or costly.

Building on economist Martin Weitzman’s classic “Pandora’s Box Problem,” Brown and his co-author, Fuqua Ph.D. student Cagin Uru, found that straightforward search rules perform nearly as well as complex algorithms. Their research shows a surprisingly simple solution: commit upfront to search a specific number of alternatives based on search costs, then simply rank what you've seen and choose the best.

What makes their approach practical and appealing is its simplicity: it requires only the ability to rank alternatives you've seen and the discipline to stop searching at the right point, not probability calculations or complex data analysis. This applies broadly, from navigating job searches to booking flights to hiring contractors.

The conversation also explores when sophisticated algorithms are truly necessary. Their research shows that, across several search settings, their simple, transparent rules perform nearly as well as those based on more complex approaches (e.g., AI), raising questions about when algorithmic solutions are worth the investment.
