Notes on the science this product stands on: persuasion research, coercion studies, declassified interrogation material, the narcissistic-abuse and recovery literature, and readings of the influence-training field — including the parts that don't flatter us or anyone else.

Reciprocity, commitment, social proof, liking, authority, scarcity. What Robert Cialdini's six principles of influence actually are, and which of them have survived the replication era intact.

Evan Stark argued that domestic abuse is a pattern of control, not a series of assaults. In 2015 England and Wales wrote that argument into criminal law. Why the shift from incidents to patterns mattered, and what it has and has not achieved.
September 21, 2026
Two sequential-request techniques, documented in 1966 and 1975, explain how a small yes becomes a large one and how a large no becomes a smaller yes. They appear in sales scripts and in abusive relationships alike.

Hear a statement twice and it feels truer the second time. The illusory truth effect, first measured in 1977, works on ordinary people, on false statements, and on things the listener already knows are wrong.
September 21, 2026
Most people believe manipulation works on others and not on them. Research on the third-person effect, the bias blind spot and the profile of actual fraud victims says that belief is itself part of the exposure.
September 21, 2026
Being cut off changes how people weigh a stranger's warmth. What the research on belonging, ostracism and social susceptibility shows, and why manipulators isolate their targets on purpose.
September 21, 2026
Love bombing is everywhere in popular writing about abuse. The research behind it is thin: one small student-journal study, a solid literature on narcissism in early relationships, and older work on intermittent reward. Here is what each supports.
September 21, 2026
Stanley Milgram's obedience experiments are the most famous in psychology. The archived recordings and files at Yale show a messier procedure than the published account, and a conclusion that survives only in part.
September 21, 2026
Hal Arkes and Catherine Blumer showed in 1985 that people keep paying for what they have already paid for. The same mechanism keeps victims inside scams and partners inside bad relationships long after the exit is obvious.
September 21, 2026
Time pressure narrows attention, simplifies judgment and switches off the slow checking that catches fraud. What decision research shows about deadlines, and why a genuine emergency almost never needs you to act in the next ten minutes.
August 3, 2026
No contact, gray rock, trauma-informed therapy, validation communities: the recovery advice circulating online, sorted by how much research actually stands behind each piece. Including the uncomfortable finding about revenge fantasies and rumination.
August 2, 2026
A fair reading of Chase Hughes' published work — The Ellipsis Manual, Six-Minute X-Ray — against the peer-reviewed record on behavior reading and influence. What aligns with the science, where the evidence runs thin, and what any buyer of any influence training should demand.
August 1, 2026
FTC data: $1.14 billion in reported romance-scam losses in 2023, median loss around $2,000, and the agency itself says most victims never report. The pipeline is standardized — love bombing, isolation from advisers, the crisis, the ask — and every stage is a trainable pattern.
July 31, 2026
Paige Sweet's 2019 American Sociological Review paper moved gaslighting from pop-psych buzzword to studied mechanism: it works by mobilizing power differences and social vulnerabilities, not just by lying repeatedly. The 1944 film, the research, and the tell that survives dilution of the word.
July 30, 2026
Dutton and Painter's traumatic-bonding research found that intermittent abuse produces stronger attachment than consistent treatment — the same variable-ratio reinforcement schedule that makes slot machines the most compulsive game on the casino floor. The mechanics, and what actually loosens the bond.
July 29, 2026
The CIA's 1963 KUBARK interrogation manual (declassified 1997) and the MK-Ultra program (exposed 1975-77) are usually invoked as proof of mind control. Read the documents and a different finding emerges: the exotic methods failed, and what worked was the ordinary psychology of dependency and dread.
July 28, 2026
Albert Biderman studied how Chinese captors extracted false confessions from American POWs without torture equipment: isolation, monopolized perception, induced exhaustion, threats, occasional indulgences. Amnesty International reprinted his chart in 1973. Domestic-abuse workers have used it ever since, because it maps.
July 27, 2026
Jennifer Freyd named the pattern in 1997: Deny, Attack, Reverse Victim and Offender. Later experiments in her lab measured both how well it works on observers and how much of its power disappears when people learn its name first.
July 26, 2026
Roozenbeek and van der Linden's Bad News study (2019) had players run a disinformation campaign for 15 minutes, then measured how much less reliable manipulative content looked to them afterward. The results, the null replication in India, and what both mean for training.
July 25, 2026
Friestad and Wright's Persuasion Knowledge Model (1994) predicts that recognizing a sales tactic as a tactic changes how it lands. Later experiments measured the effect: once a target sees the move, the mover pays a penalty. What that means for training.
