The method

A grade you can trust requires a tool willing to say no.

Child Evidence sits in the gap between legal-research databases and science search engines. It does one thing neither does: it certifies the evidentiary weight of a developmental-science claim for legal use. Here is exactly how — across 417 verified studies and 32 bridged cases.

The five gates

  1. 01

    Sourced

    Every claim is traced to verified, peer-reviewed studies. No citation is ever generated from a model's memory — each one is a foreign key to a real, human-verified source row. The system is physically unable to render a citation that isn't a real study.

  2. 02

    Weighed

    A human reviewer grades evidence strength on replication, study design, and effect size — High, Moderate, Low, Very low. The grade is stored with its criteria and rationale, never as an opaque score.

  3. 03

    Calibrated

    A second, separate axis records scientific consensus — Established, Emerging, Contested, Disputed — so a strong finding that the field still debates is never mistaken for settled doctrine.

  4. 04

    Bridged

    Each claim links to the case law that already relied on the same science. This is the slow, hard-to-copy work that turns a scientific finding into a cited, judicially-accepted proposition.

Stress-tested

Limits and counter-considerations are surfaced deliberately — what opposing counsel will say, where the science is contested. When a proposition can't clear the bar, it is rejected and never certified.

The grading scale

Two independent axes, graded by a human reviewer. These rows render from the same definitions the product uses, so this page cannot drift from the instrument.

Evidence strength

  • High
  • Moderate
  • Low
  • Very low

Scientific consensus

  • Established
  • Emerging
  • Contested
  • Disputed

What “Certified for citation” means

A claim wears the seal only when both axes clear the bar: evidence strength of High or Moderate and consensus of Established or Emerging. A claim with Low or Very low evidence, or Contested or Disputed consensus, is still published and graded — but never certified. That scarcity is what keeps the seal defensible in front of a court.

The non-negotiables

  • A human performs every act of judgment — the canonical phrasing, both ratings, the guardrails, and sign-off. AI drafts; it never publishes.
  • The public product only ever shows published, human-reviewed claims — enforced at the database, not just the interface.
  • The platform never needs privileged case facts. Claims are about the science, not your client — privacy by design.
