The aim of this study was to explore when experts trust their intuition. The Take-The-First heuristic suggests that experts generate a few options based on option validity that match the current situation and probably pick the first one they generated. In chess, the rated quality of moves can be used to analyze fast and slow decisions. We provided…

The status quo bias (SQB) is the tendency to prefer the current state of affairs. We investigated if experts (physicians) fall prey to the SQB when making decisions in their area of expertise and, if so, whether the SQB is reduced or amplified for experts compared to non-experts. We presented 302 physicians and 733 members of the general…

Forensic examiners routinely compare a crime-relevant mark of unknown origin against a single suspect's sample, which may create an expectation that the two will match. We tested how embedding the suspect's sample among known-innocent fillers (i.e., an "evidence lineup") affects expert decision-making. Experienced fingerprint examiners…

Previous research demonstrates that domain experts, like ordinary participant populations, are vulnerable to decision bias. Here, we examine susceptibility to bias amongst expert field scientists. Field scientists operate in less predictable environments than other experts, and feedback on the consequences of their decisions is often unclear or…
