Podcast Summary: Totally Booked with Zibby
Episode: Ben Rein, PhD – Why Brains Need Friends: The Neuroscience of Social Connection
Date: October 24, 2025
Host: Zibby Owens
Guest: Dr. Ben Rein, neuroscientist and author
Main Theme & Purpose
In this engaging episode, Zibby Owens interviews Dr. Ben Rein about his new book Why Brains Need Friends: The Neuroscience of Social Connection. The discussion explores the critical importance of social interaction for our brains and our well-being, unpacks the science of why loneliness is harmful, and offers evidence-based insights—grounded in neuroscience—on the primal (“surprisingly literal”) necessity of friendship and connection.
The episode aims to demystify neuroscience, making it fully accessible to a general audience and to inspire listeners to prioritize social bonds—with both humans and pets—as fundamental to happiness and health.
Key Discussion Points & Insights
1. Why Write This Book & Why Now?
[04:20]
- Dr. Rein introduces himself and describes his focus on the neuroscience of social interaction, empathy, and behaviors related to socialization (including studies of autism).
- He explains his motivation: a growing societal awareness of loneliness, which he believes is misunderstood compared to other health issues. Whereas most people know poor diet or lack of sleep are unhealthy, few grasp the severity of isolation’s effects on the brain.
- Quote:
"Smoking or being isolated is as bad for you as smoking 15 cigarettes a day."
— Ben Rein [04:20] - He aimed to write an accessible book, strictly avoiding jargon. Where technical terms appear, he provides an appendix for clarity.
2. Social Needs: Introverts, Extroverts, and Brain Benefits
[07:07]
- Zibby shares she learned through Ben’s quiz that she is a “total extrovert,” even though she enjoys her alone time—a surprising self-discovery prompted by the book.
- Ben explains how social needs vary, some are “fed” by interaction, for others it’s less appealing—but connection remains universally beneficial at a biological level.
3. Zoom, Creativity, and the Challenges of Digital Socializing
[08:00]
- Zibby highlights a favorite insight: brainstorming on Zoom, while convenient, reduces access to creative signals one would pick up in person (body language, environmental cues, etc.).
- Quote:
“You’re much better off brainstorming or doing anything creative with a group off of Zoom and in person.”
— Zibby Owens [07:45] - Ben expands: A key study showed that creativity drops when attention collapses into a screen’s “rectangle,” limiting perception of surroundings. Participants engaging in-person noticed more of their environment, which contributed to enhanced creativity.
[08:23] - Ben notes that science supporting in-person work is often misrepresented as corporate propaganda, but it’s actually unbiased research.
- Quote:
"...People were less creative when they weren't meeting on Zoom... the more they engaged with their surroundings, the more creative they were..."
— Ben Rein [08:40]
4. Everyday Interactions Matter: The Science of Micro-Connections
[09:52]
- Zibby and Ben discuss the “invisible losses” of small social interactions (like chatting with a store clerk or a neighbor), which have a measurable positive impact on us—interactions lost due to automation and digital convenience.
- Ben warns against the slide into isolation, explaining how daily micro-interactions foster a sense of safety and belonging.
[10:31] - He shares a personal anecdote from his book: An extraordinarily positive day full of kind encounters led him to feel “proud to be human” for the first time in a while.
5. The Meaning of Life and Social Bonds
[12:40]
- Zibby reads a moving passage from the book’s conclusion on the meaning of life:
"I believe that something is the love we have for each other. Without the joy we experience from our social bonds, would life be worth living?” [13:24] - Dr. Rein reflects on the radical idea that social connection is the core motivator for our species’ survival—more than evolutionary pressure alone, it’s the love and relationships themselves that keep us engaged with life.
- Quote:
“There’s nothing more powerful than the love for a child, a partner, or a best friend... Research supports this idea.”
— Dr. Ben Rein (as read by Zibby Owens) [13:44] - He adds that most of our daily activities, even entertainment consumed alone, relate to social stories or relationships.
6. Dogs, Evolution, and the Neuroscience of Inter-Species Bonding
[18:29]
- Zibby loved the chapter on dogs: How dogs have evolved with us, developing features (like “puppy eyes”) that directly trigger human bonding hormones.
- Looking into a dog’s eyes increases oxytocin in both human and dog—but the same is not true with wolves.
- Quote:
“Dogs have pretty much hijacked our human-to-human or even parent-to-child bonding systems... to make us love them.”
— Ben Rein [19:16] - Selecting for the “eyebrow” muscle is a poignant example of evolution driven by human preference—dogs who make “puppy eyes” are adopted from shelters more quickly.
- Zibby applauds Dr. Rein’s arguments against Botox, which can reduce our ability to read social signals, since mimicry (often unconscious) is central to empathy and emotional reading.
7. Emojis, Tech, and Modern Communication
[23:23]
- Zibby notes she now embraces emojis, thanks to insights from the book on non-verbal cues. Even simple symbols in texts help convey emotion and elicit empathy, compensating for missing facial signals.
- Dr. Rein confirms: Brain studies show that seeing emotional emojis can evoke neural reactions similar to real faces, facilitating communication via text.
8. How to Reconnect: Practical Advice for the Isolated
[25:18] – [30:29]
- Zibby asks what isolated listeners can actually do, especially those working from home, retired, or struggling to make new friends.
- Ben outlines three steps:
- Stop shutting out opportunities: Take calls, answer the door, don’t flake on plans—default to saying “yes” to real interactions.
- Choose the in-person option when possible: Go to the store instead of online delivery; see your doctor in person rather than via telehealth.
- Seek group activities tied to your interests: Look for social groups (using apps like Meetup) centered around hobbies. Having something in common reduces feelings of dissimilarity that hinder connection.
- He also warns: After a period of isolation, socializing may not feel rewarding at first; the brain needs to re-acclimate. Push through initial discomfort.
- Quote:
“If you are thinking... maybe I should interact more, but you have hesitations, please just try to throw those hesitations away. Everybody experiences that.”
— Ben Rein [26:58]
9. Science Communication & Dr. Rein’s Social Media Success
[30:29]
- Zibby asks how Ben built a huge online following.
- Ben recounts that his success began with casual, relatably presented short videos during Covid. Speaking to the general public “like my mom or grandma,” no jargon—making science as accessible as possible—is key.
- Quote:
“...People understood it and they felt, wow, this is science, and it's rigorous, and... it's explained at a level that I've never really been able to understand it before.”
— Ben Rein [31:25] - He reiterates the mission: Everyone has a brain and deserves to understand it; science should not be intimidating or exclusive.
Notable Quotes & Memorable Moments
-
“We are more isolated than ever before... Socializing is underserved from the neuroscience perspective.”
— Ben Rein [04:20] -
“There's nothing more powerful than the love for a child, a partner, or a best friend. Research supports this idea. There it is. Meaning of life. Boom.”
— Zibby Owens reading/quoting Ben Rein [13:44] -

“There's neuroscientific validation that... adding a little symbol could prevent a fight and keep the conversation heading in the right direction.”
— Ben Rein [24:00] -
Advice for the isolated:
“Try to recognize where you are just shutting out interaction you could be accepting... try to pick up the call, try to answer the door, try to meet with friends.”
— Ben Rein [26:32] -
On dogs and humans:
“Dogs have this ability to raise their inner eyebrows... Wolves literally don’t have that muscle... we selected for that, and now all our domestic dogs have that ability.”
