House geography instead of fighting the habit

Meta-analysis of 14 RCTs (12 with data, 1,054 children) of organizational skills training (OST) found significant moderate-to-large improvements in organizational skills (parent- and teacher-rated) and small-to-moderate reductions in inattention. OST programs include restructuring the physical environment with designated places/containers for materials, the same family of tactic as 'geografia domu' — but as part of an actively taught skill package, not an isolated environment-only manipulation.

Meta-analysis of 200+ studies / 450+ effect sizes found choice-architecture (nudge) interventions — including changing the physical micro-environment so the desired behavior becomes the path of least effort — produce small-to-medium behavior change (Cohen's d approx 0.45). Strong general support for the underlying mechanism, but the sample is general adult populations, not ADHD/autism, so the link to this target is indirect.

American Academy of Pediatrics consumer guidance recommends structuring the home environment — designated places for objects, reducing reliance on memory/willpower — as a core ADHD management strategy. Clinical consensus endorsing the approach, but non-experimental and not specific to the 'add infrastructure where things already land' framing.
