Why Brains Need Friends: The Neuroscience of Social Connection

by Ben Rein

A neuroscientist’s guide to boosting your brain health by living a more connected life, and thriving in a post-interaction world

Headlines have made clear that we are in a crisis of loneliness, but the conversation has yet to explore how spending less time interacting can impact the body and mind on a cellular level—and why this knowledge is part of the way forward. Renowned neuroscientist Dr. Ben Rein dives into the fascinating science of social interaction, revealing how our brains are wired for connection and why modern life is challenging those ancient instincts.  Through the lens of neuroscience, he explains our need for interaction and provides new frameworks for bringing more connection into our lives. Rein uncovers the mesmerizing biological factors at play in our moments together, from small talk with baristas to deep conversation with friends, and shares how to leverage this knowledge to our advantage as we seek happiness and health.

Dr. Rein’s core message in this book is that healthy brains need social interaction. He does a good enough job going into some of the research and nuance behind that message, like why virtual interactions don’t suffice, the role of empathy, etc. It’s easily accessible for someone who isn’t well-versed in neuroscience.

But the book is painfully overwritten. It’s obvious that the author had a page count to meet: Some sections are annoyingly repetitive; there are laughably unnecessary illustrations throughout the book just to fill space; and there’s just so much pointless filler.

I also hated the tone and writing style. Dr. Rein takes on this BuzzFeed, millennial, infantilizing, quirky tone that I just find nauseating. Like, “Yes, you read that right—I used compassion and zebra fish in the same sentence.” Something to this effect is at the end of every other paragraph.

Lots of really shallow moralizing throughout the book too, about how the concepts in the book could help heal humanity. “This is how we put the human back in humanity.” Give me a break.

[Ashley Singer]

I agree with this review from Amazon. Books like this are dangerous when in the hands of narcissistic people who use these as guides on how to better where a mask, love bomb, and manipulative others into seeing a false version of themselves. They do the same with psychological terms by weaponizing and using them out of context. They learn how to interact without understanding the reasons and heart behind these interactions. Similar to how many religious organizations teach people how to obey/interact without helping them develop personal discernment which guides their interactions.

As an autistic person who was recently abused by a narcissistic person (who is currently reading this book) I fear for those in relationship with her. Someone who has to read about why a brain needs friends (not to mention the whole person) is someone who doesn’t naturally experience or understand this. If you have to learn how to make a good first impression, you aren’t being your authentic self. You are lying to others and yourself.

I have a few emotionally deep relationships built on vulnerability, respect, trust, accountability, conflict repair, compassion, empathy, understanding and love. I’ve learned through experience that quality is far better than quantity (which the abuser only appears to have). The person who abused me claimed she didn’t do surface relationships. In the end she didn’t have the capacity for deep friendship. She couldn’t connect emotionally. She’d get defensive, project, or go silent. So she reads books like this to learn. Until someone develops the ability to self reflect, take accountability, and show empathy, they will never develop authentically deep relationships. Someone can be surrounded by surface relationships, appear happy, yet feel lonely. While someone who is physically alone may experience solitude and peace. This book reinforces ideals our capitalist society encourages like ableism and narcissism.

The book extolls neurotypicals and extraverts
Reviewed in the United States on October 15, 2025
Format: Hardcover
This is a very idiosyncratic critique, based on my personal reasons for buying the book, but may be important for others to know. Carl Jung reputedly said, "Loneliness does not come form having no people around you, but from being unable to communicate the things which seem important to you." This book's thesis misses Jung's point.

That's because the book is slanted toward extraverted neurotypicals; introversion is misidentified as shyness, and neurodivergents are overlooked, except to say mice "regained empathy" when given MDMA or through an alternative manual stimulation technique (183). This implies the old ableist trope: that autistics lack empathy and need to be cured. Not true at all. It also implies autistics and even introverted neurotypicals should aspire to be extraverted neurotypicals and to be surrounded by people. I have no such aspiration; my AuDHD is not a disorder nor a flaw, it is a difference in design, and doesn't need to be fixed. Maybe the mice felt the same way.”

[Susan]

I was underwhelmed by this book for a number of reasons. He makes a lot of generalizations and most of what he has to say isn't new to me. Also, as an older neurodivergent extreme introvert with social anxiety I felt personally not addressed.

First book of 2026. 5 out of 5 stars 🌟 read. This is specially important starting a new year with intentions.

First love that this book is written by Ben, who is a sci-communicator, who I even followed back when I used to use TikTok. He is very book good at breaking down brain concepts into something anyone can digest.

I love brain related books since I worked on brain myself during my PhD. This book highlights the importance of social interactions and how it can improve our quality of life. Definitely will be working on socializing more in 2026, with friends, family, and forming better connections with my students.

[Heather Browning]

There's a nice message here, and some interesting science, to show how important it is to connect with others - not just for our psychological health, but for the function of our brain itself (and its downstream effects on the body). There are some useful insights into the benefits of small moments of interaction with strangers, the value of our relationships with dogs, the ways in which drugs can help (or hinder) connection, and (perhaps most crucially) how social media and online interaction can undermine many of these benefits. I found it at times a bit 'fact heavy', and was already familiar with a lot of the research, but overall seems an important message to reinforce.

[Jen Brodehl]

3.5 Stars- I always love learning more about the brain and this book had some interesting information.

[Josh]

Why Brains Need Friends is built on a fascinating and timely premise, but it ultimately struggles under the weight of its own academic flexing. When the author's expertise serves the narrative, it’s genuinely brilliant. The standout example for me was the exploration of canine companions—specifically the biological "why" behind why dogs might actually hold more neuro-social value for us than cats. Moments like that, where a complex concept is perfectly integrated to explain a universal human bond, are where the book truly shines.

Unfortunately, these moments of elegant storytelling are often buried under an avalanche of academic noise. Despite the attempt to make neuroscience accessible, the text suffers from a flood of Greek and Latin verbiage that often feels like a performance of intellectual bona fides rather than a source of real insight. This constant need to showcase terminology disrupts the narrative flow and keeps the reader at arm's length, turning what should be an immersive journey into more of a dry lecture.

I also found the tone to be a significant hurdle. The writing style leans into a "BuzzFeed-esque," quirky millennial voice that feels a bit infantilizing, creating a strange cognitive dissonance between dense medical terminology and "Yes, you read that right!" filler. Furthermore, the book’s thesis feels like a "one-size-fits-all" approach that extols the virtues of extroverted connection while largely missing the nuance of introversion.

Ultimately, if you are willing to sift through the shallow moralizing and the stylistic quirks, there is value to be found here. But if you’re looking for deep, original insight that doesn't require wading through an unnecessary amount of "scientific noise," you should probably look elsewhere.

[Rachel Nazareth]

I found this book to be really helpful. I read it in order to help myself discover why I need to see my friends more, however it made me think of the other people in my life.

I realized how important friends are to my father, my son and my students. So many parts of this book are fascinating- like the creation of the letter by Queen Anotossa! What a cool story.

Also see that pity moves to empathy then compassion was such an eye opener for me. I also found it so interesting that text messages make us MORE depressed! Crazy

Anyway I loved the book, however it was NOT an easy read, so save it for when you have time or you are super dedicated to get through this book.

For a teacher it might be a better summer read.

[Debbie Brawn]

I initially loved this book. But the further I read, the more I realized that it is written with an implicit bias and assumption that the reader is married with children. Repeatedly referring to your spouse and your children. An entire chapter is devoted to telling you that your best opportunities for brain heath are the result of having a spouse and children. And that friendships and other social interactions don't suffice. Please do better in tone and in the way the science is presented to the audience.

[Julie]

Two stars is generous. I agree with the broad points he is making so I rounded up to two. I hated his internet-y writing style and I almost stopped reading when I read this quote.

It always bothers me when people use big words for no reason. Simpler terms almost always get the job done better. Why "utilize" or "employ" big words when we can just use smaller ones? Sure, it might feel good to "exhibit" that you "wield" a "capacious" vocabulary, but you can still be a good writer with basic language.

Jesus, where to even start with such inanity!? Oops, is that too big a word for the author? Is dumbshit more to his liking? What gets me is that those words he considers difficult are in no way difficult unless you are twelve years old and/or stupid. My hackles were immediately raised after reading that moronic complaint.

I was continually annoyed at Rein's lack of qualifying statements. What he discusses only applies to neurotypical people. Even just a sentence or two clarifying that would have been enough for me. Instead, the reader is left to believe that his argument holds true for everyone. It does not. Rein makes that common mistake so many self help authors make of assuming what works for them, will work for everyone. Just...no.

Back to his writing style, Rein writes as if he is posting to social media and not writing a book. I fear that I am in the minority here and that a lot of modern readers prefer this dumbed down writing style. I do not. I don't need bullet points and summarizing each chapter. You aren't Heidegger, Ben Rein, I can follow what you are stating no problem.

The jist of this book is basically that of the old song People from the Barbra Streisand movie Funny Girl. People need people. Not online digital representations of people but actual humans in the flesh. We need to chat with the checkout girl instead of doing self check out. We need to place an order with a waiter, not a screen. We need to talk to our neighbors, not people on Reddit. Yes! I agree with that completely. Did I need to read this book to learn that? No.

A few random quotes:

When you turn on the television, you can watch characters fall in love, obtain high social status, or defeat a shared enemy —all of which captivate the brain's social reward systems. Maybe the reason why it's so easy to ditch a night out in favor of watching TV is because we can still obtain a bit of that social reward through our devices. Perhaps we've become content with substituting these synthetic social rewards for the real deal, and consequently grown less inclined to connect face-to-face.

The mice were four times more willing to brave frightening conditions if it meant they could have a social interaction. In contrast, we found that mice with autism-related gene mutations showed no such social motivation— they were hardly willing to enter the open arm for a social interaction. HELLO DISCUSS THIS MORE.

solitary animals that prefer living alone (like tigers or lemurs) do not show increased cortisol when they are isolated. Instead, they show increased cortisol when forced to live with others. Their social needs are the opposite of ours, so their stress systems are wired accordingly. Again, DISCUSS THIS IS RELATION TO NEURODIVERSE PEOPLE'S SOCIAL NEEDS. Who is this "ours" you refer to?

a larger, more socialized brain can continue functioning at a high level even when certain synapses are pruned and lost. Indeed, a study of more than six thousand seniors found that those with larger social networks and more social engagement demonstrated greater cognitive function and slower cognitive decline as they aged. When you talk with some-one, you must be quite focused and engaged-much more than when you do other activities like watch TV. It makes perfect sense, then, that having more interactions would strengthen a brain network involved in attention, as you're flexing those attentional brain muscles. Is that true for neurodiverse elderly?

Are you satisfied with your level of social engagement?
Do you ever feel isolated?
How many days per week do you have meaningful interactions?
When friends invite you out, how often do you find an excuse to stay home?
Do you work in the office every day, or work from home some or all of the time?

When shy, reserved people pretend to be extroverted for a week straight, their mood actually drops. For the most introverted people of all, a week of extroversion can leave them feeling exhausted and out of character. short bursts of sociability can be uplifting even for those who score very low in extroversion. But as time goes on, this process wears on introverts, leaving them in worse shape.
It's almost like acting extroverted is a medicine that just one dose of can benefit all people, but introverts suffer more side effects with long-term use. Why does he act surprised that introverts find large amounts of socializing draining? That is the literal definition of the word.

If an introvert and an extrovert go out to lunch together, they will probably both leave in a better mood. But if they go on a weeklong vacation together-staying in the same hotel room and never having time apart-the extrovert will come home refreshed while the introvert will be exhausted and irritated.

Of all the amazing things humans can do with our remarkable brains, arguing online is probably one of the most useless ones. I think arguing on the internet is good for nobody, and that opinion is informed by science: Online arguments generate more negative emotions than in-person disputes and are less likely to result in consensus.

Interbrain synchrony is where the brains of two people interacting become synchronized and show nearly identical patterns of activity. It typically happens only when two people are either having a shared experience or cooperating. This synchrony doesn't happen across the whole brain. Rather, it usually involves a certain brain area syncing up between two people, and the brain region differs depending on what they are doing.

Consider the quality of your social diet and the ingredients that comprise it. Prioritize relationships that bring you joy. Walk through the grocery store and chat with the cashier. Make friends and don't flake on them. Spend more time with the elderly. Play with your dog. Be a good per-on, and please, don't get into fights on the internet.

I think it’s important to remember that reviews are subjective, and while I had a really lovely time reading this book, all of the one star reviews are equally valid in their critiques of what was either not covered by the book or in the book’s clear focus on neurotypical readers.

That said, I am “neurotypical” (as much as anyone truly fits this definition) and in a period of my life where I’m feelings extremely isolated and lonely, but desire to remedy that with more social interaction. I would easily be considered the intended audience of this book and this, I did really enjoy it. So for those feeling confused by the dichotomy of reviews….this book hits different depending on who you are and where you are in life. Something to keep in mind.

But onto the book itself — it details the chemical and resulting evolutionary results of the “social reward” or rather, how our brains reward us chemically for interacting with other people. I feel this effect personally when I’ve been home for ages and then finally have a small interaction with someone at the grocery store. Anecdotally, this totally tracks. And the reasons given in this book motivated me to seek out other, more regular opportunities for social interaction, and to not shy away from them when I’m feeling more introverted.

And I am a natural introvert, so it’s easy to just stay home and avoid things. But while this can be recharging, the book offers good evidence and reminders that you don’t have to go crazy, just be open to having interaction in the world…or you know, pet your dog.

There isn’t anything particularly actionable in the book, just a lot of decent evidence that we are on this earth to interact with each other — not to be completely and totally alone. Humans evolved to be successful in groups and we should embrace this rather than shy away from it.

I’m also a huge fan of ANY book that pushes empathy and compassion. I think many people would be well-served reading and internalizing the message laid out here, even if it has limitations around the significant variety of people who exist in the world.

Our brains may all work a little differently, but we are still here to be part of a community and in my opinion, the bigger your community in-group that you can have empathy for, the better.

[Claire Kopp]

I listened to the audio of this book and learned so much. I am fortunate to have many friends and many connections. This book emphasized how important face to face (ie coffee/ lunch, etc.) meetings are. I will try harder to nurture these friendships! Real conversations with friends and family are the best way to do this.

I listened to the audio of this book but will order the hard copy to have as a reference.

A must read!

[Mallory C]

I really appreciated the science around the positives of friends.
And friends being people that you would mostly like spending time with.
Big emphasis on the positives.

However, this books mentions a lot of social interactions that from my real life experience are not always positive. Yet somehow the author leads us to believe that there's absolutely no downside to being social. Only a small mention of introvert vs extrovert differences.

There was a massive gap I feel that was left when not mentioning the dark side of socialising. Like getting stuck in a conversation and realising it was a mistake to engage. Then frantically trying to disengage. That didn't make you feel good.

[Natasha]

Some good ideas and studies to consider.

Loved the idea of no phones at meals—otherwise you are “phubbing,” ‘snubbing’ people while using your ‘phone’ rather than focusing on the meal conversation.

Surprised by some of the crass language from this researcher an author. Was the goal to connect with young college students? I found it unsophisticated and off-putting.

Also, was a little puzzled by the chapter on setting up dogs in a role as important as children. Loved some of the benefits of animals but seemed to go too far with this theme.

[Mari Sim]

Great book to start the year with!
While listening to it, I caught myself being more mindful about my social life and starting more conversations with strangers (and I enjoyed them a lot!)

[Tom Morton]

"Interacting with a diverse group of people is associated with the greatest affects on well-being, so you may be better served by hanging out with a few different people than by spending all of your time with one person."

"Of all the amazing things humans can do with our remarkable brains, arguing online is probably one of the most useless ones...online arguments generate more negative emotions than in-person disputes and are less likely to result in consensus. You're really not getting anywhere. Ignore the trolls and avoid becoming one yourself."

There is a lot of fascinating and useful info packed in this book about how important meaningful socialization is for our mental health and well-being. Definitely worth the read!

[Asrah Habib]

I learned some things like oxytocin protects the infant on their way out during birth by slowing breathing and our body from death in a situation as severe as birth I can only say that’s important. Serotonin is what drives empathy seemingly a reward system to our brains. I understand what the author was doing writing it so it’s easy to understand and comprehend but I thought it was too simple…. If that makes sense.

[Tori Kinghorn]

I really enjoyed the early chapters, but then it transitioned to topics I wasn’t as interested in

[Scarlett]

Accessible, delightful, and based in neuroscience, this book is well-reasoned and artfully articulated. The facts support what many intuitively know: people need each other and the cost of social isolation is far too high of a price to pay.

[mal sage]

4.5 / 5

I study how built environments impact our ability to socialize with one another, and how that impacts our health and wellbeing. I picked this up thinking I wouldn’t learn anything groundbreaking, but that it would further confirm what I already know about these topics.

What I didn’t expect was to feel validated in what I go to work everyday to do, AND to be encouraged to engage more deeply with my own empathy. I loved learning the neuroscience behind how social connection impacts our brains, and why socialization is so important. This book really focuses on empathy and how critical perspective is—two things I feel I’m often screaming into the void (of my own head, at times) about.

Also- can we talk about the dog chapter? I recently lost my furry best friend and have been thinking a lot about how much more lonely I feel when I’m alone now- before he died, I’ve realized that I was never truly alone when he was around. Now, the emptiness is much more raw. I thought this feeling was primarily driven by grief—and likely much of it was and continues to be—but this chapter helped me understand that I’m actually likely experiencing lack of social connection that I used to get from my dog. It’s truly eye-opening, and in some weird ways, comforting. I definitely think a lot of my empathy comes from being around and valuing animals when I was young and that part of my brain was still developing. It was neat to hear that confirmed by actual science!

Loved this. (I can understand why other reviewers didn’t love the delivery of the writing—but I think it worked well as an audiobook.) Glad to have read it!

"You could make a convincing argument that this book is about the brain, or maybe it's about the benefits of socializing, why we should view one another as medicine. Perhaps it's about the evolutionary origins of our social disposition. But the truth is, this book is about humanity. It's about you, me, our neighbors, friends, and families--and the invisible barriers we've unnecessarily constructed between us. It's about what happens when you tune into the person sitting across from you on the train; the neighbor listening to music on his porch; the couple walking their dog across your lawn, and your dog barking defiantly in response. It's about the cashier who helps you at the grocery store; the agent who checks your bag at the airport; and the person who answers the phone when you call the bank. It's about what happens when we let the barriers between us melt and drip away; those rare moments when we see others for their best qualities instead of their worst.  It's about the emotions that overtake you when you're spellbound by a gripping conversation and you forget to check the time. It's about getting lost in connection, and letting your brain rejoice."

[Austin Kaufman]

Mission Accomplished, Dr. Rein!

I think this book set out to be a gateway into neuroscience for people who aren’t as equipped with the tools to understand that subject prior to reading. And, to that end, it did a great job!

If you are more equipped with a neuroscience background or are wanting to put this into a more formal, scholarly conversation, I can see why you aren’t thrilled with the book. To Dr. Rein’s defense though, he did achieve exactly what he set out to achieve - a highly readable book explaining the importance of social connection on a neuroscientific level more than just philosophically.

Regardless of your background, the core theme is an important one: it’s not just good for us to socialize, we NEED to in order to ensure a high quality of life and healthy aging.

My only wish is that the book got a bit more developed/nuanced (in concept and evidence base, not necessarily jargon) and trusted the reader to get smarter throughout the book even if they had no background prior to reading. I don’t have a strong neuro background, but I found myself quickly bought in to the ideas of what Dr. Rein was writing, yet eager to understand the studies more critically and in a context that I can use to launch into future reading.

Hi there! I’m Ehsan 😎
Here’s my review after reading The Social Brain and checking out some of the harsh, negative critiques 📚

1. About the book:
The entry point to the world Ben Ryan (the author) created and the way he shares his research and insights is genuinely fascinating 🤩. Perfect for anyone curious about human interaction and connection! That’s why I bought this book—but it went far beyond my expectations 😲.
It revolves around neuroscience 🧠 and social interactions in a super simple way, yet it throws in ideas that totally shocked me. I literally shouted, “WTF!” at some points.
So yes, it’s about neuroscience and social behavior—but don’t underestimate it! This book is also about love ❤️, compassion, and humanity.

2. Writing style and the author:
No exaggeration—some parts made me laugh out loud 😂. Ben drops funny, relatable moments even in serious scientific discussions, making the concepts easier to understand while keeping you entertained.
It’s not a novel, but the storytelling—especially his anecdotes—is super engaging 📖. I found myself standing up, pacing around, just blown away 🤪.
Not too childish, not too formal—perfect for readers of almost any age.

3. Accuracy of content:
I care a lot about whether information is correct ✔️. Whenever I doubted something, I double-checked and was satisfied 👍. The author also lists sources at the end of each chapter 📚. The content is simplified for easier understanding, but it’s still accurate.

4. About critics:
A: Some readers didn’t enjoy the style and tone 🤷‍♂️. If you prefer dense, ultra-formal scientific books, this might not be for you. The storytelling style is similar to Nir Eyal and Tony Robbins: fun examples, acceptable humor, no weird jargon.
B: Some complained the book talks too much about social interactions 🤔. That’s fair—most of the book focuses on interaction, love, and humanity, not deep introversion. If you’re looking for in-depth introversion insights, other books are better. The main focus here is human nature and our evolution from tribal living 🌱.

5. Who should read it?
If you’re curious about the brain and want to understand relationships better 🧠, but hate getting lost in heavy scientific terms, this book is a delicious, digestible treat. After reading a heavy book, this one felt like a refreshing, tasty snack 🥰.

Hope this helps! 🌟
With love from Iran 🇮🇷, and تمام پارسی زبانان☕

Although most of us know the importance of friendship this book dives a little deeper into the science behind what is happening at our brain level. Very interesting and a great reminder to make sure we engage with friends, family and strangers even when we feel like we don’t have the energy to do it. You are doing your brain a favour.

[Leah Broger]

As an extroverted introvert, this book felt especially resonant. I am someone who deeply needs people, connection, conversation, and shared energy, but I also reach a point where too much social input starts to feel almost physiologically loud. What I appreciated about Why Brains Need Friends is that it helps frame social connection not as a personality preference or lifestyle accessory, but as something much more fundamental. It made me think about friendship less as a nice extra and more as part of the architecture of being human.

What I liked most was the reminder that connection is not just emotional, it is biological. The idea that our brains are shaped by relationships, and that isolation is not neutral, feels both obvious and easy to forget in modern life. There was something reassuring in seeing the science behind something many of us feel intuitively. We do better with people. Not necessarily with constant access, constant noise, or constant performance, but with real connection.

[Doug R]

Examples from life and science make a case for self-improvement
Dr. Rein asserts that social interaction is a key element of a healthy brain, and a satisfying life. Then he goes on to make that case in so many compelling ways. Educational, yet heart-warming. Using comparisons to common things, Dr. Rein introduces us to neuroscience concepts, and how they influence our connections to the world. His writing style is very conversational and engaging, like sitting and chatting with a friend. He pulls from our collective experience and his own life to give relatable examples. Then, he goes on to cite many interesting published studies in easily digestible terms. And, while many studies come from renowned journals, he includes a myriad of examples from his own personal research, and that of his trusted peers. You'll understand the world, and yourself, in a new way.

[Jennifer]

First, I would like to say I was shocked with how many times I laughed, and some of his jokes were just kind of funny
Secondly, I am pleased with how the book developed. I was worried it was gonna be very too dimensional and focused on extroverts and very quasi normal people however it seemed to dive into just about every little aspect that I was hoping it would obviously there were some things definitely left out that I think should’ve been focused on more.
I will say, I am incredibly validated and feel vindicated by the research on romantic relationships and their importance in our brains. And I will continue to stand on my soapbox and tell people about that until the cows come home anyways I would recommend he almost lost all of his stars at one point and I almost gave him no stars, and he slowly started to earn them back as the book went on

[Michelle]

Oh my goodness, I loved this so much!

Dr. Ben Rein's writing takes complex neuroscience and boils it down into language we can all understand. In fact, I feel like maybe I should go into the field of neuroscience. I have a high level of confidence after reading this book that I probably shouldn't have.

Rein's point throughout the book was clear: we need to come together as a species.

As it stands right now, we are doing the opposite.

This was a highly compelling case for why we should be around each other more instead of settling into the convenience of separation, isolation, and echo-chambers.

Thank you for sending me the hardcover, Avery Books! I also enjoyed the audiobook via Spotify premium. Either format is great (although I do recommend reading the physical copy so you can meet Tony, the adorable mouse).
