Lesson 8 Development Across the Lifespan

Consensus reality holds communities together—but what happens when it falls apart? This lesson explores how culture, media, and belonging shape our shared sense of truth, and how psychological safety can determine what we’re even willing to believe.

Lesson 6 - Consensus and Culture – Shared Reality in a Fractured World

What if we’re not the contents of our mind? In this lesson, we explore disidentification and presence as psychological tools. You’ll learn how awareness allows us to observe thought without being ruled by it—and why this shift offers real contact with reality.

Lesson 7 - Awareness Beyond the Mind – Disidentification and Presence

In this final lesson, we look at how to live without needing certainty. We explore psychological flexibility and grounded curiosity as mature responses to a complex world—and offer an approach to reality rooted not in control, but in clarity, contact, and care.

Lesson 8 - Living With Openness – Psychological Flexibility and Grounded Curiosity

This recording captures Dr. Matthew Collins lecturing his undergraduate class, Introduction to Existential Psychology, about Professor RJ Starr’s paper on existential liminality. Starr’s work explores what happens when identity breaks down and we find ourselves “in between” lives. The lecture unpacks the psychological roots, cultural context, and clinical implications of liminality in a way students can immediately connect to their own experiences.

This short recording, read by Richard Price (CEO of Academia.edu), introduces my latest paper: Adversarial Social Posture: A Proposed Construct for Understanding Everyday Irritability and the Perception of Others as Inconvenience.

The paper presents Adversarial Social Posture (ASP) as a new psychological framework to explain why people increasingly experience others not as neutral cohabitants, but as obstacles. It explores the roots of impatience, grievance, and irritation in modern life, and considers the profound implications for relationships, mental health, and civic life.

Adversarial Social Posture Introduction by Academia

Trust in public health didn’t disappear—it was eroded by history, power, and emotion. This essay examines the psychology of institutional skepticism: how betrayal, control, and uncertainty shape disbelief, and why distrust has become both a defense and an identity in a world where authority often feels less earned than imposed.

Listen as Professor RJ Starr explores the emotional, social, and cognitive roots of distrust—and what it will take to rebuild faith in institutions without demanding it.

Why People Distrust Public Health: The Psychology of Institutional Skepticism

Artificial intelligence isn’t just changing work—it’s changing identity. In this lecture, Professor RJ Starr explores the psychology of replacement, displacement, and the collapse of value systems in the age of automation. What AI takes from us isn’t employment; it’s meaning. This lecture was originally delivered live to an audience and recorded for "The Artificial Era" series at PROFRJSTARR.com.

The Myth of Replacement - What AI Really Takes from Us

Living Inside the Ongoing is a reflective poem on time, consciousness, and the quiet psychology of routine. It explores how repetition, memory, and meaning intertwine as life slows its pace—how we find continuity not in achievement, but in awareness itself.
