“…The methodological/practical side effect is ecological fallacy, whereby unsupported and potentially invalid statistical inferences are made about the nature of individual children based on the (risk) profile of the group to which they belong. Additionally, representing individuals through aggregated risk categories may well facilitate better estimates of risk of reoffending, but may also do little to aid understanding of the causes of this offending and thus to guide interventions and treatments [3]; • Definity-advocates of RFR have confidently disseminated definite, clear-cut, evidencebased "explanations" predicated on indefinite, unspecific and inconsistent definitions and understandings of central concepts [30,74]. There remains ambiguity and lack of empirical consensus, even within the artefactual RFR community, over the nature of "risk factors" an explanatory concept (e.g., variously understood as causes, predictors, indicators, correlates, symptoms) and their relationship with offending (e.g., deterministic or probabilistic?…”
