For the sake of this post, when I say "lie" I don't just mean explicitly stating something that isn't true. I'm including all forms of deception and willful misrepresentation, which would include lies of omission, faking emotions, performative behavior, feigning ignorance, lies of implication, etc. I put all of those things in the same bucket as explicit lies and in some ways they're even worse because they give room for the deceptive individual to later claim "ACKSHUALLY i didn't TECHNICALLY lie because that's not exactly what I claimed" when they get found out.
Everyone lies at least sometimes. I've known plenty of people who were very clearly ND who were massive liars. I'm sure all of you have met someone like that at some point. Like people who claim to have been a navy seal and describe their last Call of Duty match as if it were their actual military service.
But I would say that knowing when and where to lie and lying convincingly is an NT trait.
Like it or not, lying is part of the meta of life. If hypothetically you never lied about anything, you wouldn't make it very far in life. Everyone is lying on their resume to some extent. Everyone lies on job applications and interviews. Everyone lies to protect their reputation and to get along with people. I do all of these things.
I've lied on every resume I've ever made. Every job interview I've ever done, with every single question I am asked, I tell the interviewer whatever would increase my probability of getting the job that I think I can get away with, no matter how removed from reality it is. I've got bills to pay.
With the job I have now, one of the questions I was asked during the interview was something along the lines of "What made you apply to apply for this position and what makes you want to work for this company?". Now the honest answer would be "Nigga, you think I wanna flip burgers as a middle aged man? No I'm applying out of desperation. I need to pay the rent otherwise I end up on the street." But obviously that answer wouldn't get me hired, so instead, I said something along the lines of "I really like working in a fast-paced environment. I know I can make a customer's day better by getting their order correct and in a timely manner. [Insert company name] is a well-established company that makes a quality product and whenever I have been a customer at this particular location the staff has provided excellent service and that's the kind of team I'd like to be a member of". Of course I was lying through my teeth, but you gotta do what you gotta do to survive in this world.
Likewise, at my workplace, I larp as being divorced so no one suspects me of being incel and it lowers my "creep tax". I don't go making up stories or go into detail but I have casually mentioned from time to time that I have an ex wife just to plant the idea in their head. Most NT incels in real life do this, I've known plenty who did because some I caught in lies and some I got to admit later on that they were lying. If you've ever met a sub5 who claimed to have a gf (or had one in the past) but never saw hard, irrefutable evidence of it, you can be pretty certain they were lying.
And look, I understand the frustration with living in a world full of lies. I know the core philosophy (the blackpill) of this forum is the pursuit of absolute, raw, unfiltered truth. But in the real world lying is just something you have to do sometimes.
I'm just glad this community exists as I'm able to be honest in a way that I could never be in the real world. I've been able to admit to things I've never told a soul about in real life.
