Last week, I held a door open for someone and they walked through without acknowledging me. Not a nod, not a smile, nothing.

As I stood there feeling invisible, I caught myself thinking the same thought you’ve probably had: “Whatever happened to basic manners?”

If you’ve been feeling like common courtesy is becoming extinct, like people are more self-absorbed than ever, you’re not imagining things.

Psychology research is backing up what many of us have been sensing for years. The social fabric that once held us together through unwritten rules of politeness and consideration really is fraying.

The science behind our social decline

Researchers call it “norm erosion,” and it’s measurable. Studies from the University of Chicago found that people today are 40% less likely to engage in simple courtesies like saying “please” and “thank you” compared to just two decades ago.

Another study tracked real-world interactions and discovered that spontaneous helping behaviors dropped by nearly a third between 2000 and 2020.

But here’s what fascinates me: it’s not that people have suddenly become evil. The change is more subtle and complex than that. Psychologists point to something called “social atomization.”

We’re becoming increasingly isolated units, moving through life in our own bubbles, often literally staring at screens that create barriers between us and everyone else.

I see it at my local coffee shop every Tuesday. The barista knows my order by heart, and we used to chat about everything from the weather to local politics.

Now, half the customers don’t even look up from their phones when ordering. They tap their cards without making eye contact, grab their drinks, and leave. The barista tells me she sometimes feels like a vending machine.

Why your brain notices these changes

Your brain is wired to detect social norm violations. It’s an evolutionary survival mechanism.

When someone breaks an expected social rule, your amygdala fires up, creating that uncomfortable feeling you get when someone cuts in line or doesn’t say “excuse me” after bumping into you.

What’s happening now is that your brain is constantly pinging these violations because they’re occurring more frequently. You’re not being overly sensitive. You’re responding exactly as your brain evolved to respond when social cohesion starts breaking down.

Think about the last time you were in a grocery store. How many people were on their phones while blocking the aisle? How many times did someone reach across you without saying anything? These micro-aggressions add up, creating what psychologists call “civility fatigue.”

The technology trap we’ve fallen into

We need to talk about the elephant in every room: our devices. Research from MIT shows that the mere presence of a smartphone on a table reduces the quality of face-to-face conversations by 20%. We’re physically present but mentally elsewhere, and everyone can feel it.

Remember when making plans meant showing up when you said you would? Now, last-minute cancellations via text have become normalized.

A Stanford study found that 67% of people under 40 consider it acceptable to cancel plans with less than an hour’s notice if something better comes along. That’s not just rude; it’s rewiring how we value other people’s time and feelings.

The constant connectivity paradox is real. We have more ways to communicate than ever, yet we’re lonelier and less connected. We mistake likes for relationships and comments for conversations.

Real human decency requires presence, attention, and effort, none of which can be delivered through a screen.

How individualism went too far

There’s nothing wrong with self-care and personal boundaries. But somewhere along the way, we confused self-care with selfishness. The “you do you” mentality morphed into “I’ll do me, and everyone else can deal with it.”

During my office years, I watched this shift happen in real-time. Collaborative meetings turned into battles of who could care less about others’ input. “That’s not my problem” became the unofficial motto.

People stopped holding doors, stopped offering to grab coffee for colleagues, stopped asking “how are you?” and actually waiting for an answer.

A Harvard sociologist recently noted that we’ve moved from an “interdependent” society to an “independent” one. The problem? Humans aren’t designed to be islands.

When we stop considering how our actions affect others, the social contract that makes civilization work starts to crumble.

Small gestures that still make a difference

Here’s something that gives me hope: decency is contagious. When you model considerate behavior, it creates ripple effects you might not even see.

Every week, I help my elderly neighbors with yard work. Started doing it after a chance encounter with a homeless veteran changed how I looked at service to others.

That veteran, despite having almost nothing, insisted on sharing half his sandwich with another person in need. If he could show that level of consideration, what excuse did I have?

Now, something interesting has happened on my street. Other neighbors have started helping out too. One guy fixes computers for free. Another woman organizes grocery runs for those who can’t drive. We didn’t plan this. It just grew from small acts of consideration.

Research confirms this phenomenon. It’s called “behavioral contagion.” When people witness acts of kindness or courtesy, they’re 23% more likely to perform similar acts within the next hour.

Your held door, your “thank you,” your patient smile when someone makes a mistake, they all matter more than you think.

Final thoughts

You’re not wrong to feel like common decency is disappearing. The data backs you up. But you’re also not powerless to change it. Every interaction is a choice to either contribute to the decline or push back against it.

Start small. Make eye contact. Say please. Put your phone away when someone’s talking to you. These aren’t grand gestures, but they’re exactly what we need.

Because if enough of us refuse to let decency die, maybe we can prove the psychologists wrong about where we’re headed.

The world doesn’t need more people worried about the decline of civility. It needs more people actively choosing to be decent, especially when it feels like nobody else is. That’s how we turn this ship around, one held door, one genuine “how are you?” at a time.
