Phobia and fear collections

A category has a rule; a collection has an argument. These 13 sets are cut by hand across the 13 categories: the phobias most often called common, the ones that are genuinely rare, the medical fears whose avoidance is itself the danger, the five types DSM-5-TR recognises, and the words ending in -phobia that name no fear at all.

Common questions

Questions about grouping phobias

What a collection is, what separates it from a category, and what the sets deliberately leave out.

What is the difference between a category and a collection?

A category has a rule and a collection has an argument. Every entry files under exactly one of the 13 categories, decided by what the fear centres on, and the category prints the rule for what belongs in it. A collection is set by hand, cuts across those categories, and exists because somebody had something to say that a filing rule cannot say.

How many types of phobia are there?

DSM-5-TR sorts specific phobia into five types: animal, natural environment, blood-injection-injury, situational, and a residual heading called other. That last one matters more than it looks, because it holds fears that are real and common and belong to none of the first four. The DSM-5 collection walks them one at a time. The types sort by mechanism rather than by frightening thing, which is why an object can move between headings without anybody’s fear changing.

What makes a phobia rare?

Two different things, and phobia lists almost never separate them. A fear can be rare because it has been looked for and found in few people, which is a finding. Or the word can be rare because nobody has ever counted it, which is not. Fear of buttons has two published estimates around three million people apart. Fear of the great mole rat has six words in an encyclopedia and a collection of quotations that all use it as a joke.

Why do some collections include entries that are not phobias?

Because the boundary is the argument. White coat syndrome is not a phobia and sits in the medical set because it is the only entry where a fear produces a number in somebody else’s records. Photophobia names sensitivity to light and sits in the set about the suffix. Delusional parasitosis is a delusional disorder filed under a phobia word. 127 of the entries here belong to no diagnosis at all, and a set that excluded them would be arguing the opposite case.

Can the same phobia appear in more than one collection?

Yes, and several do. Fear of needles is in the medical set because avoiding it costs a vaccination, and in the blood-injection-injury set because the body faints instead of fleeing. The two sets make different arguments about the same entry, and the note attached to it says which argument it is there for. A category is exclusive; a collection is not.

Do the collections cover the whole catalogue?

No, and they are not meant to. 127 of the 284 entries appear in a set. A collection is deliberately incomplete and says what it leaves out, because a set that swept in every eligible entry would be a filter with a title on it. The complete list lives in the A–Z index and in browse.
