control-group is a human-made experimental construct used in scientific methodology: a subject or condition held constant and excluded from treatment, serving as a baseline against which the effects of an intervention can be isolated. Parameters: (1) must be identical to the treatment group in all respects except the intervention being tested; (2) must be exposed to the same environmental conditions; (3) must be selected through the same sampling procedure. Persistence mechanism: institutionalized practice in the scientific method, embedded in research protocols, peer review standards, and experimental design textbooks.

Direction tested: control-group INSTANCE_OF method. Per Law 9, a control group is a specific kind of methodological technique used in experimental design — a procedure for comparison that isolates variable effects. A competent speaker would call a control group 'a method.' Nearest kind: method.
