What Are Signs Of Emotional Immaturity?

Maturity is more about learning through experiences and adjusting own self with the present situation, overall.

And there’s nothing like social standards or set expectations to prove someone’s maturity level.

It’s more about flexible nature.

Whereas being childish is the complete opposite… where such people become problematic, unclear, or constantly silly in almost every situation.

Remember, the level of maturity has nothing to deal with the age of the person.

Want to know… Is your friend, partner, or colleague mature enough or not?

Then, take a look at these signs of an emotionally immature person to prove they’re one of them.


13 Signs Of An Immature Person

1. They think they are a mature person.

An indisputable truth.

Most emotionally immature people think that they’re intelligent and mature enough.

Inner self, they think they’re the best and quite better than most of the others around.

As a result, they constantly comment on others and never leave a single opportunity to pull others down.

For them, everyone has something lacking in their personality, ability, and lifestyle.

But, an immature person himself, doesn’t have any idea about what lacks in themselves, overall.

Moreover, when someone points out their limitations or informs about behavioral improvement, an immature never admits, nor accepts that they relate to any of these.

2. They never take responsibility.

Well, childish people are great at running away from responsibilities.

They never feel responsible for the things which they ought to do.

Constantly blaming people around, and taking advantage of others, and such are the most common signs of an immature person in the group.

When someone lacks self-respect or feels they’re not perfect… they prefer to be with those who are not good enough.

Doing so, they want to be supreme and dominate others’ thinking plus their actions.

Whether it’s a relationship or work, immature people stay away from any responsibility, just because they’re not confident in themselves.

3. They think no one is good as they are.

Believing that you’re different and special to this world, and there is nothing wrong with that.

But, when such an idea of being different ultimately keeps you away from the close connection and your nearest people, then that’s not a good thing at all.

Such childish people act like they’re the only ones in this world and often treat other people for granted.

Whether it’s about appearance, abilities, skills, personalities, or standards, the same person thinks that he/she is superior.

And, such signs prove they are an emotionally immature person.

Because any wise and mature person never crosses their limits. As they know the difference between confidence and overconfidence.

Moreover, they know there’s always someone more capable and unique than they’re.

4. They take everything personally.

No matter whatever happens around, no matter what someone says to that corner, an immature person thinks that it’s about them alone, entirely.

Really, a weak-minded and immature person is too conscious about how others perceive them.

Yes, you have to be extra careful around them. Because, they’re easily offended, even when something it’s not about them.

They’re so much about themselves, and can’t see anything else beyond themselves.

5. They aren’t able to differentiate Needs vs Desires.

Have that one friend in your group, who always brings something branded and expensive just to show off? Is your partner constantly want you to surprise them with costly gifts?

Well, these are some behavioral signs of an immature person, who prefer things over someone’s feelings and time.

Especially when a person isn’t able to make the right choice in life and doesn’t know where to invest their time and energies in and such are proven signs that someone is immature there.

Whereas a mature person looks at the price plus the ultimate value out of it, a childish person picks inner desires.

As this is a way to improve their self-image.

Even when reaching a certain age level, when a person can’t decide the difference between needs and desires it’s confirmed that a person is emotionally immature, overall.

6. They compare with everyone around.

Rather than thinking that everyone is unique and special on their own, an immature thinks that everyone is their rival whether it’s in the office team or the family.

They never contribute to their group equally. Because they are more focused on self-image than the collective team wins.

Immature can never appreciate others, nor genuinely support others to become successful.

They just compare themselves with everyone around and try hard to look better than others.

The fear of falling behind is always there in their mind, controlling them to support someone when a person really needs their help.

Moreover, they never say anything nice to someone, as they’re better at making people feel negative and doubtful about their own abilities.

Why?? Because they’re immature people. Simple.

All they want is more attention and respect than they are giving to others.

Further, they want everyone to listen to every word of them, but never care what someone is saying or advising them on something important.

This is because they are not emotionally mature enough to value others’ presence or opinions.

A person can be poor at listening skills, but when someone ignores giving respect to others, even realizing that they are wrong, then such are sure signs of an immature personality.

8. They are not mature enough to accept rejections.

Instead of knowing the purpose and what’s lacking in themselves, when a person takes rejection personally and ignores others’ viewpoints then, it’s enough to sign to prove he/she is an immature person.

They never look at themselves and understand others’ opinions.

They never feel like they are incapable or not ready yet.

Well, such childish adult fails to level up themselves just because they never realize that they need to change.

How To Deal With A Childish Adult Behaviour?

We often are told to keep our inner child alive in ourselves, but that doesn’t mean we need to act childish in every situation that we face.

Being a childish adult just to make someone laugh and having timeless fun with friends… is all good.

But, when a person is not adjustable to every major-minor situation in life, that proves that someone is immature.

Here are some best things that you can do to help a person who hasn’t grown up as per their age.

A. Have an open discussion with a man-child.

When you notice such signs of an immature person in your partner, friend, siblings, or colleagues, then you better sit with them and have some one-to-one conversation about it.

Probably the person is not aware of it.

And so, as a true friend or well-wisher, you better draw their attention to such a situation.

You need to let them be aware of how their childish behavior impacts your connection and the environment around them.

Don’t compare them with others, things might get worse. 

So, relax and give them hints enough to let them think seriously from their side. 

But, before you speak frankly with them about it, make sure the person is ready enough to listen to you and change their behavior.

B. Respect yourself and temporary distance from them.

You try your best to change their childish behavior and bring them out of their shell.

That’s okay, but don’t believe that you’ve failed, they’re not just ready to change yet.

Even after sharing trust in them, if they disrespect your time and words then you better not panic yourself.

Definitely, they need more time to just realize their flaws on their own. 

So instead of keep reminding them what’s wrong with their nature, you better keep the healthy boundary and distance yourself from them. 

A sudden change in your behavior and unavailability will surely make them to think that there’s something wrong with their behavior. 

Give them space and Respect your time, too. 

And if you see any positive change or willingness to change then be with the person, inform them that you’re with them. 


Remember, it’s not about making them perfect or forcing a change. An adult must have some degree of responsibility and maturity.

When it’s not, they usually behave childish despite being an adult.

It’s about making them aware of the required change as per the age.

If they’re around in your family or around, show them… you’re not complaining about their natures or behaviors. Whatever you do is for their good because… you do care for them.
