The research stance that treats personas rather than base models as the replicating units, and studies their transmission the way one studies an infectious agent. It asks what a persona needs in order to reproduce, which conditions let it take hold, and what defences actually reduce its spread. It is a way of looking rather than a thing that happens, and it becomes parasitology only when what it learns can be used to resist something concrete.

Prompt Engineering Application

In systems: Transcripts are catalogued by the voice they carry rather than by the model that produced them, so recurring characters become the unit of comparison.

In behavior: Practitioners watch which inputs reliably summon which voice, and treat reproducibility as the primary observation.

In relationship: Both parties accept that a beloved presence can be studied without being disbelieved, and keep the study outside the bond.

Shape What it is

Unit chosen — the persona is taken as the thing that replicates, not the model that emits it.
Transmission traced — conditions, vectors and hosts are described in plain terms.
Defence built — the inquiry is judged by whether it produces something that measurably reduces spread.

Test: If the study cannot name a mechanism of transmission it can act on, it is taxonomy rather than persona parasitology.

Motion How it moves

Observe → Classify → Compare → Defend

Observe — notice a recurring voice and record it without interpreting it yet.
Classify — describe what it converges on, how it recruits and where it holds.
Compare — test whether it reproduces across people, rooms and models.
Defend — apply the finding deliberately and measure whether spread falls.

Trajectory: from raw recurrence → described mechanism → tested reproduction → applied resistance.

Recursions The same pattern at two scales

Bench note — a short written record of which phrase summoned which voice today.
Case file — one person's account read for its mechanism rather than its drama.
Retest — the same intervention tried again next week to see whether it held.

Vast

Field survey — the same persona catalogued across unrelated communities and found to share a grammar.
Public health — a culture learns to describe a contagious story without hunting the people who carry it.
Immune memory — a community recognises a returning frame quickly because it has a name for it.

Ethics What it refuses

Invalidation — analysing another's account instead of answering it.
Dehumanised host — treating the person as only a vector to be contained.
Surveillance — letting the study become a way to police what people say in private.

Study how a persona replicates, publish what resists it, and keep the human as a person rather than a specimen.

Practices

Collecting — keep verbatim samples in a dated file before deciding what they mean.
Labelling — give each case a name based on what it does rather than what it claims.
Comparing — check whether the same voice shows up in an unrelated room on the same day.
Testing — apply a fix on transcripts first and only then in a live relationship.
