OPSIS, an early-warning instrument for public attention

Field notes

The instrument reads headlines, public conversation, private search, and search-box phrasing in a fixed order, calibrating each topic against its own routine before labeling movement. A displayed sample dated 2026-09-08 reports economy running above normal for 14 days and pairs topic scores with ranked changes, monthly search figures, literal questions, and conversation counts. The example replaces entity names, so the page demonstrates the format without exposing the monitored subjects.
