NIS Indices: Sensors, Not Truth Values
Read discourse, expectations and representation separately.
A methodological handout on the purpose of NIS sensors, interpreting their time series and the limitations of uncalibrated indices.
Intent
NIS compares different responses to a shared event. Relevant aspects include not only individual values but also persistence, temporal order and divergences between information spaces.
What Is Observed?
X and Reddit provide separate discourse samples. Prediction markets show capital-weighted expectations subject to specific resolution criteria. Contrarian signals flag anomalies; PRI describes expected and observed political representation.
What Do We Obtain?
Timestamped index snapshots with original measurements, sources, topic/event associations, coverage and method version. A snapshot is an intermediate product on the way to a substantiated hypothesis.
Time Series and Smoothing
Change, velocity, baseline and fast or slow EWMA series can reveal different temporal patterns. Smoothing reduces short-term fluctuations but can conceal peaks, so raw values are retained. Half-lives are parameters to calibrate, not natural constants.
What Cannot Be Inferred
Platform discourse does not represent the general population. A market price is not proof of an event, an anomaly is not proof of inside information, and a representation gap is not a popularity score. Insufficient data remain visible as a gap.
Relationship to ROS
Signals are checked against primary sources and additional evidence. Hypotheses and assessments enter the shared Research State; later corrections preserve the earlier information state.
