KNOWN translates developmental research for parents, educators, and the people shaping childhood. That only works if readers can see how much weight a claim can bear. This page explains how KNOWN evaluates evidence, how it labels what it publishes, and what happens when a claim changes.
Published September 2026.
Every framework element, essay, research note, and tool carries one of these labels. The label tells you exactly what stands behind each claim.
Supported by substantial converging evidence across studies or methods. Experts may argue about mechanism or magnitude, but the core finding is not in serious dispute.
Example: responsive caregiver relationships support healthy development.
Credible, consistent evidence from research, applied within the ages and contexts the studies cover.
Example: controlling rewards can weaken intrinsic motivation, depending on the task, the age, and how the reward is used.
KNOWN's integration of Established and Supported research into one practical model for parents and educators.
Example: the KNOWN developmental map, which connects conditions, practices, and capacities.
Before a claim is published, KNOWN records the answers to the following. The record is internal; a summary appears on the page where the claim is made.
A claim is never upgraded without a dated note explaining what changed. Labels can be downgraded, and that is published too.
KNOWN invites review of its framework and evidence labels from researchers and practitioners in the fields it draws on. Reviewers are credited alongside the work they reviewed, and a reviewed label is never upgraded without a dated note explaining what changed.
Answer a few questions about your child and what feels hard right now. You will get a plan and the tools that fit.
