Abstract

fetched live from OpenAlex

In intelligence, law enforcement, and, increasingly, organizational settings there is interest in detecting deception; for example, in intercepted phone calls, emails, and web sites. Humans are not naturally good at detecting deception, but recent work has shown that deception is actually readily detectable - using markers that humans don't see but which software can readily compute. Pennebaker's model suggests that deceptive communication is characterized by changes in the frequency of four kinds of words: first-person pronouns, exception words, negative emotion words, and action words.We investigate what can be learned about the deception model by applying it to a large corpus of Enron emails. We show that each of the four kinds of words in the Pennebaker model acts as a separate latent factor for deception, rather than having their effects mixed together.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
