Pip: If you have ever assumed that behavioural scientists just count things and phenomenologists just feel things, congratulations — you have a philosophy degree from the school of caricature.

Mara: Today we are working through a post by surtymind that challenges exactly that assumption, asking what observation really means when you put Applied Behavioural Analysis and Merleau-Ponty in the same room. Let's start with what that collision actually looks like in practice.

Phenomenology, ABA, and What Observation Actually Means

Pip: The central tension here is about whether observation is ever truly direct — and what gets lost in clinical practice when we assume it is. The post sets up two traditions that seem opposed but share a surprisingly similar blind spot.

Mara: The post opens its case for why measurement matters in ABA with a striking analogy: "Not to define precisely and to measure these behavioural excesses and deficiencies, then, is a fundamental error, it is akin to the malpractice of a nurse who decides not to measure vital signs."

Pip: So measurement in ABA is not a bureaucratic preference — it is framed as an ethical obligation, the difference between accountable care and guesswork dressed up as clinical judgment.

Mara: Right, and the post is genuinely sympathetic to that. ABA tracks countability, temporal extent, and temporal locus — when a behaviour occurs, how long it lasts, how often. That granularity is what lets practitioners demonstrate that a treatment actually worked rather than just felt like it did.

Pip: But then Merleau-Ponty walks in and says the person doing the measuring is not a thermostat.

Mara: Exactly the post's point. It draws on Ponty's Phenomenology of Perception to argue that a support worker witnessing self-injurious behaviour is not a passive instrument. Past memories flood forward, emotional responses tighten the body, and all of that shapes what happens next — none of it captured in the behaviour count.

Pip: And the post is careful to say ABA's measurement emphasis is laudable — the problem is the air of objectivity it lends to situations that are irreducibly intersubjective.

Mara: The post puts it plainly: any behaviour change in a service user cannot be fully understood unless you also account for the staff member's history with that person, their emotional state in the moment, and the culture of the group they work in. No behaviour occurs in isolation.

Mara: That points directly toward the question of what kind of knowledge clinical practice should be built on — which is where the broader naturalistic picture becomes unavoidable.

Pip: The deeper provocation here is that rigour and lived experience are not opponents — the real error is mistaking a measurement system for a complete account of reality.

Mara: And that is a tension that runs well beyond disability services. Worth sitting with until next time.
