Thanks for your comments SC. Yes, there are definitely nuances.
I came across an old BPDfamily forum thread asking “Are BPDs easily manipulated?”
https://bpdfamily.com/message_board/index.php?topic=285314.0;allGoogling around, I see that this question/theme is discussed quite a lot on various forums and in articles. The more common opinion (from both people with and without BPD) seems to be that people with BPD are more manipulable. But there are certainly people who hold otherwise.
A typical example of a comment I came across from someone with BPD:
“What people with BPD wish FPs [favorite persons] knew about living with this disorder?
M: I wish they knew how fragile we are, how easily manipulated or taken advantage of we are, and I wish they would be cautious of that.”
I tend to think that in general, people with BPD may be more manipulable than average. But I think maintaining control might generally be difficult given BPD volatility, engulfment fears, etc.
I also looked up articles on risk factors for joining cults.
In an article on Bustle, psychologist Dr. Perpetua Neo listed nine personality traits that confer susceptibility to joining cults: 1. people who want to feel validated (having a dire need for validation/approval), 2. people who are seeking an identity (who feel their identity isn’t stable), 3. people who are looking for someone to follow or emulate, 4. people who are seeking meaning, 5. people who have schizotypal thinking, 6. people who are highly suggestible, 7. people who tend to blame others (don’t take responsibility for their own actions), 8. people who are always angry, and 9. people who have very low self-worth.
To my eye, five of the nine (1, 2, 7, 8, 9) match common BPD traits. However, I wouldn’t weight this psychologist’s opinion too heavily, since it’s not the result of a scientific study, etc.
I came across a few scientific articles on cult joining, but none of them included proper psych diagnoses of the cult joiners studied. But given the characteristics found to be risk factors, I wouldn’t be surprised if cult membership was enriched for people with BPD.
In “Cult membership: What factors contribute to joining or leaving?” (2017), the authors noted:
“Members presented with social and affective vulnerability….
we highlighted a high prevalence of psychiatric and addictive disorders during the year preceding commitment to the group: anxiety disorders (51.6%), mood disorders (45.2%) and addictions (12.9%)….
a problematic familial relationship that exists before joining the cultic group could be a vulnerability factor for commitment (Buxant et al., 2007). Almost 23% of members had notable conflicts with their family during the year preceding the commitment.”
In “Joining and leaving a new religious movement: A study of ex-members’ mental health” (2008), the authors write:
“some previously existing vulnerabilities reported by members (insecure attachment in childhood, few social relationships, negative life events)….
In our previous study on NRM members (Buxant et al., 2007), participants reported a fragile past, i.e., insecure attachment history, high need for closure, and depressive tendencies….
On average, participants reported an insecure parental attachment in their childhood, both with the father and with the mother.”
As an aside I’ll mention that my one full biological sibling has severe BPD and belongs to a cult.
