Some people just don’t seem to understand how to act in public.

They say the wrong things, make people uncomfortable, or completely miss social cues. And the truth is, social intelligence plays a huge role in how we connect with others.

Having low social intelligence doesn’t mean someone is a bad person—it just means they struggle to read the room and respond appropriately.

So if you notice someone displaying these behaviors in public, chances are, their social intelligence could use some work.

1) Interrupting constantly

We all know someone who just doesn’t let others finish their sentences.

They jump in mid-conversation, talk over people, and always seem more interested in speaking than listening.

This kind of behavior shows a lack of awareness and respect for others. Conversations should be a two-way street, but constant interrupters make it all about themselves.

People with strong social intelligence know how to listen, wait their turn, and make others feel heard. If someone can’t do that, it’s a clear sign they struggle with social awareness.

2) Oversharing personal details

I once met someone at a coffee shop who, within five minutes of talking, told me about their breakup, financial struggles, and a fight they had with their boss.

I barely knew them, but they acted like we were lifelong friends. It was overwhelming.

Of course, being open and honest is great—but there’s a time and place for everything. People with high social intelligence understand boundaries and can read the situation before diving into deeply personal topics.

If someone shares too much too soon, it often makes others uncomfortable and can push people away rather than bring them closer.

3) Avoiding eye contact

Eye contact is one of the most important ways we connect with others. It shows confidence, attentiveness, and respect in a conversation.

In fact, studies have shown that maintaining eye contact for about 3 to 5 seconds at a time helps build trust and engagement.

People with low social intelligence often struggle with this. They might look around the room, stare at their phone, or avoid eye contact altogether, making interactions feel awkward or disconnected.

While too much eye contact can feel intense, avoiding it completely can make someone seem uninterested or even untrustworthy.

4) Talking too loudly

We’ve all been in a public place where one person’s voice seems to dominate the entire room.

Speaking too loudly can come across as disruptive and inconsiderate, especially in quieter settings like restaurants, libraries, or public transportation.

Socially intelligent people are aware of their surroundings and adjust their volume accordingly. But those with low social intelligence often don’t notice (or don’t care) that their voice is drawing unwanted attention.

Being mindful of volume isn’t just about politeness—it’s about respecting the shared space and making sure everyone feels comfortable.

5) Ignoring personal space

Everyone has an invisible bubble around them, and when someone gets too close, it can feel uncomfortable.

Personal space varies depending on culture and context, but in general, people expect a certain amount of distance—especially when talking to strangers or acquaintances.

Those with low social intelligence often stand too close, lean in too much, or invade others’ space without realizing it. This can make people feel uneasy or even trapped.

Socially aware individuals pick up on body language cues and adjust accordingly, ensuring that interactions feel natural and respectful.

6) Not acknowledging others

Few things feel worse than being ignored.

Whether it’s failing to say “thank you” to a cashier, not greeting a coworker in the hallway, or looking at a phone while someone is speaking—these small actions send a big message. They make people feel unimportant.

Socially intelligent people understand that acknowledgment matters. A simple nod, smile, or greeting can make someone’s day. It shows respect and basic human decency.

But those with low social intelligence often overlook these moments, missing opportunities to build positive connections with the people around them.

7) Dominating the conversation

There’s nothing more frustrating than talking to someone who only seems to be waiting for their next turn to speak.

Conversations should feel balanced, but some people make everything about themselves—telling long-winded stories, steering every topic back to their own experiences, and barely letting others get a word in.

It can be exhausting. It makes you feel like your thoughts and experiences don’t matter.

Socially intelligent people know that good conversation is about give and take. They listen as much as they speak and make sure others feel included. But those with low social intelligence often don’t notice (or don’t care) how one-sided their interactions have become.

8) Making inappropriate jokes

Humor can be a great way to connect with others, but not all jokes land the way they’re intended.

People with low social intelligence often make comments that are offensive, poorly timed, or just plain awkward. They might joke about sensitive topics, read the room incorrectly, or fail to notice when others are uncomfortable.

A well-timed joke can bring people together, but an inappropriate one can push people away. Socially intelligent individuals understand boundaries and know when humor is welcome—and when it’s better to stay silent.

9) Not noticing when others are uncomfortable

Social interactions aren’t just about words—they’re about body language, tone, and unspoken cues.

People with low social intelligence often miss these signs. They don’t notice when someone is trying to leave a conversation, when a joke didn’t land, or when their behavior is making others uneasy.

Being socially intelligent isn’t about being perfect—it’s about being aware. It’s about paying attention, reading the room, and adjusting accordingly so that interactions feel natural and comfortable for everyone involved.
