About HAx
HAx curates actionable experiments drawn from TED Talks and rates them against published research. Our goal is to bridge the gap between inspiring ideas and evidence-backed practice.
Evidence Rubric
Every experiment and talk on HAx receives an evidence rating based on the quality and quantity of supporting research.
| Level | Meaning | What to expect |
|---|---|---|
| High | Multiple high-quality studies (RCTs, meta-analyses) | Strong confidence in the claimed effect |
| Moderate | Credible research with some limitations | Good support, worth trying |
| Preliminary | Early-stage or small-sample research | Promising but unconfirmed |
| Mixed / Contested | Conflicting results or active scientific debate | Interesting but interpret with caution |
| Narrative / Conceptual | Expert reasoning, not empirical study | Thought-provoking, not empirically tested |
Editorial Posture
HAx does not endorse any single experiment as a guaranteed solution. We present the evidence as it stands, including contradictory findings and methodological limitations. Our role is curation and translation, not advocacy.
Citation Policy
Every evidence rating links to the studies that informed it. Where possible, we link to open-access versions or DOIs. We update ratings as new research is published.
Update Cadence
Evidence ratings are reviewed when significant new research is published. We monitor replication studies, meta-analyses, and systematic reviews relevant to each experiment. The "last reviewed" date on each page indicates when the evidence was last assessed.
