We recently found out that our somewhat new neighbor has been lying—about things that seem totally random and unnecessary. I get that small white lies happen from time to time, but when it’s over something trivial, it really makes you wonder why. That curiosity sent me down a bit of a rabbit hole, trying to understand why people lie, even when there’s no clear reason. In this post, I’ll break down some of the most common motivations behind lying and see how they might apply to what’s going on in our own backyard.

One of the first things that came up in my search was the idea that people often lie as a form of self-protection. This means they may choose to be dishonest in order to avoid punishment, escape negative consequences, or shield themselves from emotional or physical harm. Sometimes, lying is a way to maintain personal boundaries and protect their privacy. It can also be a defense mechanism used to prevent embarrassment, rejection, or conflict. In many cases, the lie isn’t meant to deceive for personal gain but rather to create a sense of safety in a situation that feels threatening or overwhelming.

My perceptions: Our neighbor told us that his mother was living with him while she was battling cancer, but we recently learned that she’s actually his wife! This surprising twist made me think about what might have motivated him to tell a different story. Since he’s foreign-born, it’s possible that cultural differences or a fear of being judged as an outsider influenced his choice. Maybe he worried that revealing the truth would lead to rejection or misunderstandings within the community, especially if he feels like a minority. I suppose cultural pressures and the need to navigate unfamiliar social expectations can lead people to create stories that feel safer or more accepted.

Another common reason people lie is to make a favorable impression on others. This can stem from a desire for admiration, acceptance, or approval, especially in social or professional settings. In these cases, individuals might exaggerate achievements, downplay flaws, or fabricate details to appear more interesting, successful, or likable. Sometimes, lying is a way to “save face”—a method of avoiding embarrassment, preserving dignity, or preventing social discomfort. It can also involve crafting a false persona, where someone presents an idealized version of themselves to fit in, gain status, or avoid rejection. At its core, this type of lying is often about managing how others perceive us, even if it means temporarily sacrificing authenticity.

My perceptions: We also have a strong feeling that the Chinese food he’s been bringing over isn’t homemade but actually from a nearby restaurant. The packaging looks almost identical to typical takeout containers, and it seems a bit surprising to me that someone who’s Korean would focus on preparing Chinese cuisine. My husband thinks it’s a friendly gesture meant to help build a connection, and while we appreciate the effort, we’d honestly be just as happy to keep things casual and simply share a beer with him in the backyard.

A third common reason people lie is for instrumental purposes—using dishonesty as a tool to achieve a specific goal. This can include lying to gain rewards, secure advantages, or avoid undesirable outcomes. For example, someone might fabricate a story to get out of trouble, obtain a promotion, or win favor in a situation where the truth wouldn’t serve their interests. Lies can also be used to manipulate others, influencing their decisions or actions for personal benefit. Additionally, people may lie to shift blame or responsibility onto someone else, deflecting accountability to protect their own reputation or position. In these cases, the lie is often strategic, driven by the potential payoff rather than emotional reasons.

My perceptions: Another thing that puzzles me is his career story. He told us he’s a flight nurse working night shifts but also runs a catering business on the side. While we’ve touched on the food situation already, what strikes me as more unusual is how often he seems to be awake during the day, given his claim of working nights. Recently, he even asked my husband about job openings at his workplace, which wouldn’t be too strange on its own—except their careers couldn’t be more different. My husband works in a field completely unrelated to healthcare, so I’m not sure if this was just a casual question or if there’s some hidden motive behind it. It feels like there could be an underlying connection or reason I’m missing, something beneath the surface that hasn’t quite come to light yet.

Lastly, there are several other reasons people might lie that don’t always fit into the more common categories. Some lies are told to protect others—out of kindness, empathy, or a desire to shield someone from pain or distress. Others may lie to avoid conflict, choosing to keep the peace rather than spark an argument or create tension. In some cases, lying becomes more deeply rooted and habitual, developing into a pattern over time. There are also instances of pathological lying, where individuals lie frequently and compulsively, often without clear benefit or reason. These kinds of lies can stem from underlying psychological or behavioral conditions, making the dishonesty less about the situation and more about the person’s internal struggles.

My perceptions: While I struggle to see how any of these lies are meant to protect us or keep us safe—unless, of course, this is rooted in some kind of cultural misunderstanding—I’m starting to suspect that he might be a habitual or even compulsive liar. From what I’ve learned, this kind of behavior isn’t easy to change without professional intervention. Small lies may seem harmless, but to me, they often signal something deeper going on beneath the surface. It creates a sense of unease, a feeling that there could be bigger issues or more significant truths yet to be revealed. Because of that, I don’t feel inclined to invest my time or energy in building a relationship with someone who can’t be honest about even the little things.

Ultimately, we might never truly know why people lie, especially when their reasons don’t seem to add up. Everyone has their own story and motivations, many of which stay hidden beneath the surface. While exploring these common reasons has helped me make a bit more sense of the situation, it’s clear that some mysteries don’t have easy answers. Sometimes, the best we can do is acknowledge the complexity and accept that not everything will be fully understood. Let me know your thoughts in the comments!
