The scientist/practitioner in behavior analysis: A case study
Sidman’s 1970s field story shows you can blend fading, chaining, and live data to solve problems anywhere.
01Research in Context
What this study did
Sidman (2024) retells a day in 1970. He was asked to help a man with severe disabilities learn a job task.
No lab, no grant, no team. Just Sidman, the man, and a workbench. He used fading and backward chaining on the spot.
He tracked data with scrap paper and a pencil. The story shows how a single behavior analyst can act like a scientist in real time.
What they found
The man mastered the assembly task step-by-step. The brief data sheet showed steady progress each hour.
More important, the vignette proves you can make quick, principled, data-based choices outside the clinic.
How this fits with other research
Virues-Ortega et al. (2021) describe Azrin doing the same thing a decade earlier. Both men left the lab, tested ideas, and shared results fast.
Jimenez-Gomez (2025) updates the idea. He says today’s culture wars demand the same scientist-practitioner spine, plus cultural awareness.
Pritchett et al. (2022) push further. They argue the role now includes sharing power with clients and communities, not just tracking data.
Coy et al. (2024) give a tool for the talk side. Their LADER script helps you stay evidence-based when caregivers push back.
Why it matters
You may never face a 1970 workbench, but you still make fast choices in homes, schools, and stores. Sidman’s story reminds you to measure, think, and adjust on the fly. Pair that habit with today’s cultural and ethical checks, and you keep the scientist-practitioner title alive.

03Original abstract
This article is a transcription of Murray Sidman's presentation at the annual meeting of the Society for the Quantitative Analysis of Behavior in May 1998. It describes the development (from 1965 to 1975) of behavior-change programs implemented outside the animal laboratory to benefit humans before such application was established formally as an entity derived from the experimental analysis of behavior. The presentation illustrates the use of an inductive method in practice, where working with a fluid behavior stream entails making intervention decisions on the spot. Examples include fading and backward-chaining procedures in the establishment and stimulus control of novel actions. Sidman also discusses the certification of practitioners and the interaction between client and therapist and between basic and applied endeavors. The latter define what is contemporaneously described as translational intervention. It is noteworthy that Sidman's presentation was at a meeting attended by both practitioners and scientists.
