Fear of Feathers

Why Wiktionary could not verify pteronophobia

In September 2010 the word was put through Wiktionary's request-for-verification process, which exists to establish that a term is actually used rather than merely listed. The editor who raised it noted that it is not in the Oxford English Dictionary, that it produces a few OneLook hits and a smattering of results on Google Scholar. A second editor searched Google Books and found two citations meaning fear of feathers, which he said exhausted every occurrence there. Two is below the threshold, and the entry failed.

That is an unusually precise measurement of how thin a phobia word can be while remaining in general circulation. The catalogues that carry pteronophobia carry it on the authority of other catalogues. Ronald Doctor, Ada Kahn and Christine Adamec give it a definition and three cross-references in the third edition of their encyclopedia of phobias in 2008, and no case, no prevalence and no treatment beside it.

What the surviving pteronophobia citations were doing

Both surviving uses are incidental. Brent Filson's 1986 book on phobias mentions in passing the people whose fear of birds is combined with a fear of feathers, and describes a woman in her thirties with the combined form who was too frightened to go outside. Josie Hadley and Carol Staudacher, writing on hypnosis in 1989, use the word as a throwaway example of a fear nobody needs to treat: a person can live easily with pteronophobia, aulophobia or batrachophobia, since one simply stays away from feathers, flutes and frogs.

That second use is worth keeping, because it is the standard argument for ignoring the rare phobias and the 2022 case is the standard rebuttal.

How pteronophobia became the fear of being tickled

A third strand runs alongside. A 2005 children's novel by Anna Dale has a character say that pteronophobia is the fear of being tickled with feathers, and a photograph uploaded to Flickr in 2013, a king vulture, carries the same gloss as its title. Being tickled with a feather is not what any reference work says the word means, and the variant circulates anyway, on image captions and list sites, alongside the one the books record.

What the only published pteronophobia case describes

A. Abubakar and Z. G. Habib described a twenty-year-old undergraduate, identified as Miss RI, who had spent a year in severe, episodic and uncontrollable fear at the sight of a feather. The reaction the report records ran to:

• a raised heartbeat
• shortness of breath
• trembling
• a choking sensation
• a dry mouth
• heavy sweating
• screaming
• collapse

Her mother described her screaming and jumping out of a room on detecting one. There was no history of convulsions, no loss of consciousness and no previous psychiatric disorder.

The avoidance cost her a career. She was studying the biological sciences and the laboratory work involved animal feathers, so she changed her course. She stopped visiting places where a feather might be, and the possibility of one in a room was enough to keep her out of it. Her family keeps turkeys, pigeons, ducks and chickens in the backyard, and she stopped going into the backyard. The report is explicit that she does not fear the birds. She fears what comes off them.

That distinction is the whole of the entry's case for existing separately from ornithophobia. The bird is not the object. What is left when the bird is removed is.

Why pteronophobia has a cure but no prevalence figure

Miss RI was treated with systematic desensitisation, the graded exposure and relaxation procedure Joseph Wolpe introduced in 1958, and she responded. The report's figure shows what she made after the intervention: a hand fan, built out of a feather. Chin Choy and colleagues reviewed forty-five years of the technique against specific phobias in 2007 and found it effective, which is the general result the authors lean on.

Every prevalence figure in the paper belongs to specific phobia as a category rather than to this fear:

• the World Mental Health Survey figures reported by Klaas Wardenaar and colleagues in 2017, a lifetime rate of 7.7 to 12.4 per cent and a twelve-month rate of 2 to 8 per cent
• Oye Gureje and colleagues on Nigeria in 2006, a lifetime rate of 5.7 per cent and a twelve-month rate of 4.1 per cent
• a 2022 survey of Nigerian adolescents, 6.4 per cent, with twice as many girls as boys

None of that measures pteronophobia. Nobody has, and a term with one published case has nothing to count.
