Applied Behavior Analysis is a Science and, Therefore, Progressive.

Petrovic et al. (2016) wrote a position paper. They asked: how do we keep ABA a living science when working with kids with autism?

The authors looked at years of practice trends. They warned that rigid, one-size-fits-all protocols can freeze the field.

The paper says ABA must stay flexible. Clinicians should tweak programs fast when data say the child is not moving forward.

They argue that cookie-cutter plans hurt scientific honesty and short-change meaningful outcomes for each child.

The call for flexibility builds on Rutter et al. (1987). That older paper defended ABA’s seven core dimensions; the 2016 piece keeps those but adds the demand to evolve.

Vollmer et al. (2025) extend the idea. They tell you to bake ongoing social-validity checks into every phase of treatment, not just at the start.

Allen et al. (2024) push it further. They spell out neurodiversity-affirming tactics—identity-first language, assent loops, autistic voices on the team—showing what flexible, client-driven ABA looks like in real life.

Ahearn (2025) seems to clash. That paper urges behavior analysts to defend ABA without public doubt, while Petrovic et al. (2016) warn that blind loyalty kills the self-correction that makes ABA a science. The gap is tone, not facts: one asks for advocacy, the other for ongoing critique inside the same tent.

You can adopt the spirit today. Run your next session as usual, then add one quick probe for assent and one social-validity question for the parent. If either answer is shaky, change the program before the next visit. That tiny loop keeps your work data-driven, client-centered, and truly progressive.
