compulsive and pathological liar — explained — 1 brief investigation

the receipt wallet, the certified letter, the voicemail full at eight months. compulsive and pathological liar, the search returned, are different routes to the same drawer. the_ex drives a volvo now, which i hear about from people who should not be telling me. a meeting could be a 3-line email. so could most confessions.

which is a long way of saying: a search engine sent me here, this morning, with the two adjectives stapled together as if they were the same animal. they are not. they are routes. the routes share a destination — the drawer of certified letters, broadly — but the road to each one is wired differently, and i’d like, on this tuesday, to take both roads slowly enough to mark which is which.

writing this from the desk. carla is in the all-hands on the third floor, which always overruns by twenty minutes because somebody asks a clarifying question that is, in fact, a complaint. i have, by my own reckoning, the rest of the morning.

REFLEX. AND. ARCHITECTURE. ARE. NOT. THE. SAME. ROOM.

compulsive and pathological liar, the working sketch

so here is the working sketch, drawn at this desk, in pencil, on the back of a folded receipt from the wallet. a compulsive liar lies the way a person who bites their nails bites their nails — without thinking, without planning, often before they have decided they need to. the lie comes out a half-second before the truth would have. there is a small jolt. they keep going. it is, in its way, an autonomic response.

a pathological liar, by the long-form definition i have been quietly piecing together from the kind of websites that explain things in numbered boxes, is a different machine. they lie persistently, often elaborately, across many contexts, and their lies frequently produce no clean external benefit. there is a pattern. there is texture. there is, sometimes, a private self-mythology that, with enough time and enough audiences, the liar themselves begins to half-believe.

both are members of the broader family of dishonest behaviour i have, over time, mapped on the general field guide to the word “liar”. that is the pillar. this post is the conjunction. the conjunction is doing more work than people realise.

the public confusion is reasonable. the words travel together because they sound alike, and because, in casual usage, both end in “liar” and start in latin. in the press, they get used as synonyms. they are not synonyms. they are neighbouring rungs on a ladder, and the ladder has a direction.

the ex would have ranked these, briefly

the_ex, who i don’t talk about often and won’t, here, talk about by name, had a short, brutal taxonomy of liars. she would, at parties, classify a person within twelve minutes of meeting them. she got it right roughly nine times in ten. i was, at the time, impressed. i should have been worried. anyone who can rank that fast is keeping a list, and lists are, in their way, evidence.

her separation between compulsive and pathological was, as far as i can reconstruct from memory and one half-remembered conversation in a kitchen, this: compulsives lie when asked. pathologicals lie when not asked.

that is, on reflection, almost exactly right. the compulsive needs a prompt — a question, a small social pressure, a mild interrogation about whether they got to that thing. the lie comes out under that mild duress. the pathological does not need a prompt. the pathological will, in the middle of a perfectly calm conversation about the weather, volunteer a story about being briefly a session musician for a band whose name you recognise. nobody asked. they offered. the offering is the rung.

i was, at parties, a compulsive at most. i would say “i’m fine” when asked, which is the smallest, oldest, most permitted lie in the language. i did not, in 2019 or any other year, volunteer that i had been a session musician for anyone. that’s the line. she clocked the line. i still respected the taxonomy. i sometimes still use it.

now she drives a volvo. with seats that adjust in fourteen ways, by reports i should not be receiving and yet receive. that is, you’ll notice, an aside that is also a small omission. the omission is the rung i live on.

the certified letter i opened by mistake

last month, in a moment of unusual administrative courage, i opened a certified letter. i meant to open a different one. they were stacked. the certified ones live, broadly, in the drawer of certified letters, which is the second drawer down on the left, and i had reached for what i believed was a takeaway menu. the menu was, in fact, a certified letter from an entity that i had been carefully not-acknowledging for approximately eleven weeks.

i read it. the letter was polite. the letter was firm. the letter referenced a previous communication, also certified, which i had, in a separate act of administrative courage in the spring, signed for and then placed, unopened, in the wallet. the receipt wallet has, in addition to receipts, a small cache of envelopes i could not, at the time, deal with. it is a wallet by name only. it is, functionally, a holding pen.

standing there with the opened letter, i had a small philosophical moment about which kind of liar i had been. i had not, technically, lied to anyone. nobody had asked me, on a tuesday, whether i had read the certified correspondence. but i had been operating, for eleven weeks, as a person who had not received the letter — which, on a strict reading, is a lie i had been telling, mostly to myself, by leaving the document in the wallet rather than the desk.

that is not pathological. that is barely even compulsive. that is, on the rung-chart, a small architectural lie of omission, performed quietly, alone, with no audience. ignorance is, in this case, financial therapy. it is also, broadly, the cheapest therapy on the market.

the voicemail, still full, still patient

the voicemail has been full for eight months. eight. i checked. that is, by any reasonable measure, a long time for a voicemail to be full, and it is, by any honest measure, also a kind of lie — not one i tell with my mouth, but one the voicemail tells on my behalf, in a polite robotic voice, every time someone tries to leave a message.

“this mailbox is full.” the system says. the system means: the user has chosen to be unreachable here. the user has not, in fact, said this to anyone in person. the user has, in fact, told several people he is, broadly, available. the voicemail and the user are not on the same page.

this is, by my own definition, neither compulsive nor pathological. it is, instead, what i would call structural. the lie is held in place by the geometry of my phone, not by any particular sentence i have spoken. nobody asked. nobody volunteered. the architecture lies for me.

which is, on reflection, the closest the ordinary working liar — me, on a tuesday — gets to the pathological end. not in the elaborate-story sense. in the sense that, after enough months of letting the voicemail be full, i have, in some private corner of the head, almost begun to believe that the voicemail being full is a fact of weather rather than a choice i continue to renew every morning by not clearing it. that is the slip. that is the country the pathological liar lives in full-time. i visit. i don’t move there. as far as i know.

why both words exist and neither sticks alone

both words exist because they describe two different failures of honesty, and either one alone leaves a hole. compulsive captures the small, twitchy, under-pressure liar. pathological captures the long-form, world-building, narrative liar. the casual reader, looking at someone who lies a lot, often cannot tell which they are watching, because the symptom — frequent untruths — looks the same on the surface.

but the engine is different. the compulsive engine is anxiety; the lie comes out because the truth feels, in that moment, dangerous, and the body produces a small fiction faster than thought. the pathological engine is, depending on the case, identity, attention, or a long-built private cosmology that the liar has, by long use, mistaken for a memory.

both have close cousins in gaslighting, which is a related but distinct manoeuvre — gaslighting is a sustained programme of denying somebody else’s perception, and it can be performed by either kind of liar. the gaslighter is, in fact, often a pathological liar wearing strategic clothes. but gaslighting is its own building. for our purposes today, it lives next door, and i mention it only because anybody investigating one of these words tends, eventually, to investigate the other. you don’t end up here without ending up there.

here is, if you want a quick rule of thumb, my own working test. ask: is the person lying because the truth would, in that small moment, cost them something? that is compulsive. is the person lying when the truth would have done just as well, with no clear cost saved? that is pathological. it is not perfect. nothing is. but it sorts most of the people in your life, in my experience, with a high enough hit rate to be useful.

for cinematic context, the working public reference is the 2002 caper film about a teenage cheque forger who flew commercial planes he did not own, which lives at the elaborate end of the pathological rung. the small daily compulsive liar, by contrast, lives in every break room in the western world. the same shelf, very different volumes.

verdict, the conjunction is doing all the work

the verdict, written from this desk, with carla still on the third floor and the all-hands now eleven minutes over, is this: the conjunction matters. compulsive and pathological liar are not interchangeable. they describe two distinct rungs, and the search engine that put them together has, in its own quiet way, contributed to the confusion the rest of this post has tried to undo.

for further field-work on the smaller, quieter end of the chart, see the working definition of the pathological liar specifically. for the meaning of the milder, habit-shaped end, see the field note on what habitual liar actually means in practice. for the rung that is, in fact, immediately under pathological, see the longer post on the pathological liar as a category. those three, together with this one, cover most of the territory most people search for when they get sent here by a confused engine on a tuesday.

i remain, on the rung-chart, where i was: an omitter on a busy day, a strategist on a calm one, a compulsive only when caught in a kitchen, and not, by any honest measure, pathological. the voicemail being full is, on reflection, not the same as inventing a band. one is administrative cowardice. the other is identity construction. i can live with the first. the second i don’t have the energy for.

all-hands let out. carla walked past with two folders and an expression. the second folder is, traditionally, the one with the actual problem in it.
