Face Blindness Test

A quiet look at how you place the people you know once the usual setting is gone. It shows how recognition works for you, not how good you are at it.

A white goose stands on a flagstone garden path between blooming flowers and a stone wall lined with enamel pitchers.

You know that feeling when someone greets you warmly and you cannot tell who they are? This is not a test of whether you are paying attention or being polite. It shows how you place the people you know once the usual setting is gone. For each scene, pick the answer closest to you right now. It takes about four minutes, and at the end you get a short reading of what your recognition leans on. What does it lean on when the setting changes?

0%
Someone you know turns up on a street you have never seen them on, walking toward you. What does the first second look like?
You spent an evening with someone new: you remember the name, the job, a story they told. How soon does the face itself feel familiar?
You call one person by another's name, and everyone nearby stares, since the two look quite different. How alike do two people have to be before you mix them up?
A person you know steps out of a doorway where you would never expect them. Whose face do you know at once?
You spot someone you know at a distance or in passing. What tells you who they are first: the face, or something else?
Everyone in a group is dressed alike, or standing in the same spot. How many people does it take before you lose who is who?
Someone you know well turns up with something changed: new glasses, a haircut, a different shirt. How big does the change have to be before it throws you?
You are face to face with someone you know well, close up and in good light. How much does the face alone tell you who it is?
You wave at a stranger who turns out not to be who you thought, or you look straight past someone you do know. What does it take for a slip like that?
A film or a series has several characters who look a bit alike. At what point do you lose who is who, and then the story?
You are at a crowded gathering, hunting for one particular person among others who look similar. How many look-alikes does it take before your greeting goes astray?
A stranger looks a great deal like someone you know, or someone you know turns up somewhere absurd. How well do you keep the two apart?
You are heading somewhere you could bump into someone you should know, though it is unlikely. How unlikely can it be before a jolt of worry shows up?
An invitation lands, and your first thought is about faces: what if you greet someone wrongly. How small can the gathering be and still make you hesitate?
Before an event you do want to attend, you might warn people about faces or rehearse a line for a mix-up. How small an occasion gets that treatment?
Think of a room where you might run into someone you should recognize, small or crowded. How calm are you at the door?
A person you know easily in their usual place turns up somewhere else. How different does that new place have to be before you miss who it is?
A familiar face tilts, catches odd light, or pulls an expression you have never seen on it. How small a change makes it hard to know?
Someone you have met before comes over to say hello. What do you need handed to you before it clicks: a name, a reminder of where you met, the whole story?
You catch sight of a person you know in a place that has nothing to do with them. Do you know them?

How this test works

Where the questions come from, what the scale rests on, and why the result is not a diagnosis.

Self-reported everyday face recognition across five areas: recognizing known people, leaning on non-facial cues, errors in both directions, the social cost of recognition situations, and how recognition holds up across settings.

Methodology

Real assessments of face recognition use photographs and a key of right answers: faces are shown and the answers are checked. This page has no pictures and no key, so it cannot do that job. What it offers is a way to put everyday experience into words, like questionnaires that researchers use before objective testing begins.

The questions touch on mix-ups in either direction, worry or avoidance around meeting people, recognition in a new place, angle or light, the cues besides the face that carry the load, and how quickly familiar people get placed. They were written for this test, and the score bands belong to it alone.

Answers given this way show a strongly marked picture well and separate milder experiences poorly, so the result works as a prompt for reflection and not as a ranking. It reflects one sitting and cannot say whether a pattern is lifelong or came later. This condition is identified through a person's own account together with several independent objective tests, and no single test, this one included, is enough by itself.

For reading beyond the test, see the NHS page on face blindness and the APA definition of prosopagnosia.

This test is not a diagnostic tool or a replacement for a specialist. It does not diagnose face blindness (prosopagnosia) and cannot confirm or exclude it. It shows only how the person answering describes everyday recognition. A specialist, using photo-based testing and a conversation, is the one who can assess it.

Questions

Does it mean something is wrong with me if faces are hard to recognize?

No. Recognizing faces works differently from person to person, and it says nothing about intelligence, attention or upbringing. What makes a conversation with a specialist worthwhile is not the fact itself but how much room it takes up in your daily life.

How many questions does this test have?

There are 20 questions, each with five answers to choose from.

Can this test tell me if I have face blindness (prosopagnosia)?

Only a specialist can say. They work with photo-based tests and a conversation, and a questionnaire cannot stand in for that. What this one gives you is your own description of everyday recognition. If it leaves you wondering, a neurologist is the person to ask, and the methodology section links to reading on the subject.

Can face blindness be cured?

What helps in daily life is practical: leaning on a voice or a familiar detail, saying your name first, asking others to do the same. These are ways of managing, since no treatment restores recognition itself.
