Child Evidence

Whether placing a maltreated child in foster care produces better or w · Child Evidence

child welfare / foster placement vs. remaining at home

Whether placing a maltreated child in foster care produces better or worse outcomes than leaving the child at home is genuinely unresolved: rigorous quasi-experiments using the same identification strategy reach opposite conclusions, effects apply only to "marginal" cases at the placement threshold, and the science supports neither a presumption for nor against removal.

For the Court

Contested. For children at the margin of placement, rigorous natural experiments disagree on whether foster care helps or harms; the science supports neither a pro- nor anti-removal presumption.

What This Claim Does NOT Say

Does not claim foster care is generally harmful or generally beneficial; high-quality quasi-experiments reach opposite directional conclusions.
Applies only to marginal cases at the placement threshold, not to children facing clear, severe, imminent harm where safety requires removal.
Does not establish a causal effect for any individual child; the estimates are local average treatment effects with wide uncertainty.
Does not support a presumption either for or against removal; placement remains an individualized best-interests/safety determination.

Scope — Where It Holds

Built on instrumental-variable natural experiments that exploit the quasi-random assignment of investigators. Doyle (2007, 2013) found marginal children fared BETTER at home (less delinquency, higher earnings); Gross & Baron (2020) found foster care IMPROVED safety and education; a meta-analysis found no clear difference between foster children and at-risk children who stayed home (Goemans et al., 2016). Findings are local to children at the margin of placement and do not speak to clear-cut severe-harm cases.

Observational
Using effectively random assignment of investigators as an instrument, children on the margin of placement had BETTER long-term outcomes (less delinquency, fewer teen births, higher earnings) when they remained at home, especially older children.
Bearing on this claim: Doyle IV: marginal children fared BETTER at home (delinquency, teen birth, earnings).

Precedent Bridge

Santosky frames removal as grave state intervention requiring heightened proof; the contested causal evidence on placement-vs-home counsels that removal turn on individualized harm, not a general presumption.455 U.S. 745 (1982)

Limits & Counter-considerations

Estimates are local average treatment effects for marginal cases and do not generalize to severe-harm cases; they depend on system quality, child age, and the counterfactual home environment; and unmeasured heterogeneity likely explains the cross-study divergence.
