Methodology
AIFI publishes a lagging daily close of fear already in public AI coverage. The live product labels the methodology version as AIFI-3. Same inputs under that version replay to the same number.
Daily close
- Scale: 0–100.
- Timing: one lagging daily close (not an intraday live feed).
- Stamp: the JSON field
as_of/as_of_utcmarks which day the close belongs to. - Provenance: closes may be tagged (for example
backcast) when historical series are produced under the same rules.
Bands
The UI maps the close into five bands (inclusive lower bound, exclusive upper bound except extreme, which runs through 100):
| Band | Range |
|---|---|
| calm | 0 – <20 |
| watchful | 20 – <40 |
| elevated | 40 – <60 |
| fearful | 60 – <80 |
| extreme | 80 – 100 |
Component family (AIFI-3)
The public close JSON lists weighted components. Labels and relative weights as published in /data/index.json:
- GDELT AI-fear articles (weight 0.32)
- Wikipedia AI/safety views (weight 0.18)
- Hacker News AI gravity (weight 0.18)
- Reddit AI discussion (weight 0.18)
- News RSS AI-fear hits (weight 0.14)
On any given day a component may be observed, warming, or missing. Effective weights can shrink when a source is unavailable; coverage metadata in the JSON reports eligible sources and weight. Do not treat a missing component as a fabricated value.
Public machine-readable outputs
- /data/index.json — latest close, band, change vs previous, components, version, notes.
- /data/history.json — date / close series for charts and research.
- /embed.svg and /embed.png — embeddable snapshots.
Limits. AIFI measures fear already present in public coverage signals. It is not a forecast, not advice, and not a claim about private or proprietary sentiment. Methodology details beyond the public JSON and this page may evolve; the version field identifies the rule set for a given close.
