Abstract
Microtargeting is a market segmentation strategy (identifying submarkets of individuals and groups for marketing or political purposes) based on an individual's behavioral, geodemographic, and psychographic characteristics. It has its origins in the use of geodemographic and psychographic cluster analysis and was developed in part because of its effective use in the marketing of products and services to niche audiences and its perceived usefulness in political campaigns during the twenty‐first century. Its beginnings lie in the geodemographic work of social reformer Charles Booth in London during the 1880s. Significant subsequent developments include the work of urban social ecologists and the development of models of urban geodemographic structure, the introduction of new statistical models of factorial ecology and cluster analysis; the exploitation of large census databases and geographic information systems (GIS) to segment zip code and postal code geography, and the introduction of social media (Facebook, YouTube, Twitter, among others) to increase temporal and spatial granularity. Recent developments have included concerns over privacy, misinformation, transparency, and market dominance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
