Five Reasons to Lie

I’ve seen a lot of pushback against dishonesty in the EA and LW communities (this post and this post), and some promotion of radical honesty, but I don’t think I’ve ever seen a steelman of lying. I recently spoke with a rationalist friend about this, and it seems that some of the most basic arguments for lying seem to be simply skipped over. Although they may seem a little tongue-in-cheek, and I, of course, see the value of honesty in virtue ethics/​ game theory contexts, I think arguments against lying tend to simply ignore these fairly obvious and rational reasons to lie.

So, as someone with a history of lying (mainly as a teenager) that I’m neither ashamed nor proud of, and a few lovely friends who haven’t dropped the ball like I have, and are committed lifelong compulsive liars- allow me to offer five reasons to lie:

1. Lying can be highly efficient. Imagine I want to sleep with someone, but my girlfriend doesn’t want me to sleep with someone. This would seem to be a dilemma where our interests clash, but then I realise, aha! My girlfriend doesn’t really not want me to sleep with other people, she just doesn’t want to find out that I’ve slept with other people (actually true, I’ve asked her). If only there were some way of fulfilling both our preferences?! My friend, there is a way: the noblest of lies! Whether in the workplace or in a marriage, the truthful man is imposing countless inefficiencies upon himself with his childish adherence to honesty.

2. Lying is theatre, Lying is fun. Being your ‘authentic self’ can be interesting, and radical honesty can be refreshing if you’ve spent a lot of your life being forced to be inauthentic, but honesty clearly limits the scope of self-expression for someone with a decent imagination. Drawing a firm line between theatre/​storytelling (where lying is okay) and real life (where it isn’t) seems bizarre and horribly unnatural. As Shakespeare said, “All the world’s a stage”, so why limit our creative outpourings to such a narrow sliver of human interactions as theatre? If you’ve ever had to travel through a new country, telling everyone you meet the same old story about how you’re a student on a gap year, you’ll very quickly get bored, but lying gives you a chance to be a persecuted politician, a failed astronaut, a fishmonger on a sabbatical, or a 19th-century traveller who has been mysteriously transported to the present. If you’ve never tried telling a stranger an elaborate lie about yourself, honestly (well...), you have lived a deprived existence.

3. Lying can make you sound better than you are. As a man of modest achievements and questionable merits, I often feel embarrassed when describing myself to others, especially in elite, high-status communities like the EA/​ rationalist community; but there is a tool available to the low-status man- the self-aggrandising lie! For example, I told many of my friends in primary school that I invented the Double Decker chocolate bar. For a 9-year-old with no major achievements to my name, I could finally experience the status of an inventor, a child prodigy, a boy who has made a difference to the world! And all without having invented a thing! Talk about win-win.

4. Lying is a social lubricant. The classic defence of lying here- if someone asks you: “Does my bum look too big in this dress?”, you don’t want to be honest and respond: “Yes, you look like a whale who has swallowed another, much larger whale.” (Assuming, of course that this is the actual visual effect created by the dress). You could remain technically honest and weasel out of it by saying: “Compared to the Alcyoneus galaxy, it’s positively minuscule”, but lying is clearly the optimal strategy here. It gives you the ability to either say: “No, it looks just wonderful” (a little boring, but effective) or to dazzle your interlocutor with a change of topic, and say: “Did you know that I’m actually personally responsible for the demise of the semi-colon?”.

5. Lying is excellent mental exercise. According to personal experience, and a peer-reviewed meta-study I just made up, the mental skill required to maintain multiple different, often contradictory lies with various individuals and social groups keeps you constantly on your toes, and probably prevents dementia or something. One of my best friends, despite his mind being addled by a marijuana habit, still manages to maintain fairly contradictory versions of the last decade of his life with interlocking friendship groups. Bonus points if you have completely different personas and life stories in different languages.

I’m sure we can think of other brilliant reasons to try adding a few more lies into our lives, but these are some examples to start with.

Edited to stress that the dress comment is in fact an honest perception.
