01Research in Context

01

What this study did

Fraley (1998) wrote a narrative review. The paper asked: Can we study cognitive fallacies with pure behavioral tools?

The author argued yes. Matching-to-sample tasks plus feedback or rewards can measure errors like base-rate neglect.

02

What they found

The review found no new data. Instead it mapped how to turn mentalistic fallacies into operant experiments.

It listed tools you already know: concurrent schedules, auditory beeps, points, clear contingencies.

03

How this fits with other research

Kutzner et al. (2008) later ran the exact test Fraley (1998) asked for. Adults in a lab ignored base rates and tracked cue frequency instead. The single-case data confirm the review's hunch.

Pierce et al. (1983) showed humans already follow the matching law. Fraley (1998) simply reapplies that setup to 'irrational' choices.

Thomas et al. (2026) systematically reviewed brief auditory feedback. Their cross-disciplinary scan backs up E's tip that a simple click or beep can serve as a cheap, effective consequence.

04

Why it matters

You can swap mind-talk for measurable behavior. Next time you see a client 'jump to conclusions,' set up a quick matching-to-sample game. Present two samples, deliver points for correct picks, and log the choices. You will turn a fuzzy fallacy into clean response data that graphs nicely at team meeting.

03Original abstract

The area of judgment and decision making has given rise to the study of many interesting phenomena, including reasoning fallacies, which are also of interest to behavior analysts. Indeed, techniques and principles of behavior analysis may be applied to study these fallacies. This article reviews research from a behavioral perspective that suggests that humans are not the information-seekers we sometimes suppose ourselves to be. Nor do we utilize information effectively when it is presented. This is shown from the results of research utilizing matching to sample and other behavioral tools (monetary reward, feedback, instructional control) to study phenomena such as the conjunction fallacy, base-rate neglect, and probability matching. Research from a behavioral perspective can complement research from other perspectives in furthering our understanding of judgment and decision making.
