Fear of Being Tied Up
Merinthophobia
Merinthophobia is a fear of being bound or tied up, and the objects it attaches to include seatbelts, tape and thread. That range is the clue to what is actually feared.
Why the object is restraint rather than rope
The Greek merinthos is a cord or a string, and the name suggests a fear of one specific material. The avoidance described is much wider. A UK professional-development reference lists the things a person with the fear may avoid seeing as well as touching: rope, string, seatbelts, handcuffs, netting, cord, wire, thread, tape and chains.
A seatbelt is on that list, and so is thread. Neither will hold anybody. What they have in common with handcuffs is not strength but the idea of being fastened, and the same source states the point directly: merinthophobia is often related to a fear of losing control, which is one of the beliefs Claustrophobia runs on.
That also explains the odd inclusion the same source makes. A person with the fear may be afraid of being restrained even where the restraint is there to keep them safe, and even where there is no real prospect of it happening. A rational fear of being tied up exists and belongs to kidnapping. This is the other thing.
Why escape acts trigger the fear
Wikipedia records a symptom that no other entry in this catalogue has. A person with merinthophobia will be very uncomfortable watching an illusionist escape from being bound, and may feel sick while doing so.
An escape act is designed to be watched with the outcome guaranteed. The performer will get out; that is the point of the form. For the reaction to fire anyway, the trigger has to be the depiction of restraint rather than any danger to anyone, which puts the fear closer to the disgust-driven aversions than to the fears of harm.
The same article records the two routes in:
- an incident in which the person was bound, either as a joke or deliberately
- simply seeing someone else bound
It adds that the trauma of such an occurrence often stays with a person for life.
How merinthophobia hides inside needle phobia
The Cleveland Clinic page on needle phobia, last reviewed in 2022, lists the possible components of that fear, and merinthophobia is one of them: a fear of being restrained, which an injection can trigger. That is a hospital reference treating this term as an explanatory part of a commoner condition rather than as a curiosity.
It is a useful observation for anyone reading the needle phobia literature. Some part of what looks like a fear of the needle is a fear of having to hold still while somebody else does something, and the two respond to different handling.
What the diagnosis rate is worth
A UK professional-development reference puts the number currently diagnosed at fewer than one per cent of the population, and the same source's account, which adds that the figure may reflect a lack of awareness of the condition rather than its rarity. That is a diagnosis rate rather than a prevalence, and for a term that no diagnostic manual carries as a heading, a diagnosis rate is close to meaningless.
Treatment is described as counselling, hypnotherapy and psychotherapy, with no trial cited for any of them. The 2008 encyclopedia of phobias, which carries most of this vocabulary, gives the term a single line and no treatment at all.
Told apart
Often confused with Fear of Being Tied Up
- ClaustrophobiaBoth are fears of not being able to move, and the reference literature routinely places them together. Claustrophobia needs a space; this needs only a fastening, which is why a seatbelt qualifies.
- Fear of NeedlesThe Cleveland Clinic lists merinthophobia among the components of trypanophobia, because an injection requires holding still. Part of what presents as a fear of the needle is a fear of the restraint.
- Fear of Being TouchedBoth fire on contact that the person has not chosen, and both can be set off by a medical procedure carried out for the person's benefit.
Common questions
Questions about Merinthophobia
- Why would a seatbelt trigger it?
- Because the object is the fastening rather than the strength of it. The avoidance list given for merinthophobia runs from rope, handcuffs and chains to seatbelts, netting, wire, thread and tape, and thread will hold nobody. The same source states that the fear is often about losing control.
- Can it fire while watching someone else?
- Yes, and the example Wikipedia gives is unusual. A person with the fear will be very uncomfortable watching an illusionist escape from being bound, and may feel sick doing it. An escape act is a performance in which the outcome is guaranteed, so what sets the reaction off is the depiction of restraint rather than any danger.
- What has it to do with fear of needles?
- The Cleveland Clinic lists it as one of the things that can underlie needle phobia, because receiving an injection involves being held still. Some of what presents as a fear of needles is a fear of restraint wearing a medical setting.
- Has the number of people with it been established?
- Fewer than one per cent of the population is currently diagnosed, according to a UK professional-development reference which adds that the number may reflect how little the condition is known rather than how rare it is. Since no manual carries the term as a heading, a diagnosis rate for it does not measure much.
