A written communication carries two kinds of information: what it says, and what its construction reveals about the person who wrote it. The first is obvious. The second, read with discipline, can be just as informative, particularly when authorship is uncertain or intent is in question.
Linguistic analysis examines written and verbal communication to assess authorship indicators, credibility and potential threat posture. It is applied to professional documents, to anonymous correspondence, and to communications of concern, the messages that sit somewhere between nuisance and genuine threat and demand a judgement about which.
Using structured linguistic and behavioural techniques, we look for consistencies and deviations: the stylistic fingerprints that suggest authorship, the shifts that suggest more than one hand, the markers that distinguish a vented frustration from a stated intention.
Where threat is a question, we weigh escalation risk through factors such as frequency, specificity, targeting and behavioural leakage. A communication that becomes more specific, more personal and more frequent over time is telling a different story from one that does not, and the difference is often legible in the language before it is anywhere else.
A particular strand of this work concerns impression management: the ways individuals and organisations construct and project a version of themselves, and what shows at the seams when that projection diverges from reality. In high-profile contexts, political, media and corporate communications, the constructed impression is, in effect, the product, and the distance between message and intent can carry significant consequences. Reading that distance, carefully and without overclaiming, is a discipline in its own right, and one we continue to research.
As with all behavioural work, the output is clear findings and reasonable inferences, not declarations of certainty. The purpose is to support decisions on escalation, protective measures and engagement, giving the people who must act a sounder basis for doing so.
Read alongside credibility assessment and behavioural analysis, linguistic analysis adds a dimension that is easy to overlook and difficult to fake at length.
