In this episode Dr. Shepard explores Dunbar’s Number, the idea that humans can meaningfully maintain about 150 social relationships. Drawing from Robin Dunbar’s book "How Many Friends Does One Person Need?," Dr. Shepard explains the social intelligence hypothesis that links neocortex size to social-group limits, breaks down the layered structure of relationships (from 3–5 closest friends to 1,500 recognizable faces), and describes how frequency and intimacy shape each circle.

The episode also examines how gossip expands social knowledge, how social media and smartphones change our sense of community and parasocial ties, and the friendship formula (investment, emotional closeness, trust, support) for building deep connections. Dr. Shepard shares personal anecdotes about community, presence, and how phones affect conversation depth, and offers practical advice on moving online acquaintances offline to develop real friendships. He ends with reflections on choosing where to invest your time and the unique, uncodified nature of friendship.

In this episode Dr. Marcus C. Shepard breaks down three internet era relationship behaviors: ghosting, orbiting, and breadcrumbing through what they mean, why they’ve become common, and how they affect both romantic and platonic connections.

Ghosting is the sudden withdrawal of communication without explanation; orbiting is staying digitally connected (likes, story views, occasional DMs) without real contact; breadcrumbing is giving minimal, inconsistent attention to keep someone hopeful without genuine investment. Dr. Shepard explains these behaviors are usually unethical and ineffective except in cases like abuse where cutting contact is necessary.

The episode uses real examples and research based reasons people ghost ranging from lack of interest, to timing, and attachment styles. Shepard also describes how orbiting and breadcrumbing create mixed signals, false hope, and emotional confusion.

In the Ask Dr. Shepard segment, a new student asks how to make friends at the start of a semester. Practical tips include arriving early to class for casual “social snacking,” using group projects to build rapport, inviting classmates to meet outside of class to move beyond the classmate role, and joining campus clubs or student groups to meet people with shared interests.

Overall, the episode encourages accountability and clearer communication online and offline, offering both definitions and actionable advice to foster healthier interpersonal connections.

In this episode Dr. Marcus C. Shepard walks through Sherry Turkle’s "Reclaiming Conversation" and explores how smartphones and social media shift us from deep, face-to-face conversations to mere, shallow connections. He highlights terms like fubbing, whole-person conversation, solitude, punctuation in texting, maximizers vs. satisficers, multitasking vs. unitasking, intellectual serendipity, and weak vs. strong ties to explain why presence matters for empathy, creativity, and community.

Dr. Shepard shares personal examples—holiday gatherings, hosting friends, and classroom observations—to show how putting phones away fosters intimacy and meaningful dialogue. He discusses how technology creates an illusion of companionship, undermines solitude and self-reflection, encourages performative self-presentation, and changes expectations in dating and conflict.

The episode closes with practical takeaways inspired by the book: slow down, schedule solitude, create phone-free sacred spaces for conversation, practice unitasking, welcome difficult dialogues, avoid all-or-nothing thinking about technology, and remember that speaking and listening are skills that can be improved. These steps help reclaim conversation and build deeper community in an increasingly connected world.
