Searching for the sunk cost fallacy

Friedman (2007) · Experimental Economics · Read the paper

Friedman and colleagues went looking for the sunk cost fallacy in a controlled setting and largely failed to find it. Participants played a computer game in which they dug for treasure on an island and could pay a cost, sometimes high and sometimes low, to move to another one. If the fallacy operates as described, people should stay longer on islands that were expensive to reach. Across eleven variations, including different visual presentations, different ways of learning an island's value and different cost levels, the effect was surprisingly small and largely unmoved by the psychological factors thought to drive it. The paper is a useful corrective in a literature where the phenomenon is usually treated as established and universal. It does not show that sunk costs never influence people; it shows that in a clean, repeated, low-stakes setting the effect is hard to produce. This vault cites it alongside the meta-analysis and the original demonstrations.
