At Sandstone Psychology, we often work with individuals and families who are asking a difficult but important question:
“How did things get to this point?”

Whether it’s a child struggling in school, a workplace that feels unsafe, or a relationship that has quietly become unhealthy, the answer is rarely about one “bad” person. More often, it’s about how environments, expectations, and unspoken roles shape behavior over time.

This week in psychology history offers a powerful—and still relevant—example.

A Brief Look Back: The Stanford Prison Experiment

In mid-January 1972, psychologist Philip Zimbardo launched what would become one of the most well-known (and controversial) studies in psychology: the Stanford Prison Experiment.

Healthy, well-adjusted college students were randomly assigned to play the roles of “guards” or “prisoners” in a simulated prison. What was supposed to last two weeks ended after just six days.

Why?

Because ordinary people began behaving in ways that were deeply distressing:

• Guards became controlling, harsh, and emotionally detached.
• Prisoners became anxious, withdrawn, and hopeless.
• Emotional distress escalated rapidly on both sides.

No one was instructed to be cruel. The behavior emerged from the situation itself.

Why This Matters in Everyday Life

While this study took place decades ago, its lessons show up daily in therapy rooms, classrooms, homes, and workplaces.

1. Roles Shape Behavior—Often More Than We Realize

When people step into roles—authority figure, caregiver, employee, “problem child,” leader—they often begin acting according to what they believe that role demands.

We see this when:

• Parents feel they must always be strict, even when it doesn’t feel right
• Children internalize labels placed on them
• Adults remain in unhealthy systems because “that’s just how it works”

Part of therapeutic work is helping people step back and ask, “Is this role serving me—or limiting me?”

2. Loss of Individual Identity Reduces Empathy

In the experiment, prisoners were given numbers instead of names. Guards wore uniforms and sunglasses. These small changes made it easier to stop seeing others as fully human.

This same process happens when:

• A child becomes “the difficult one”
• An employee becomes “just a number”
• A diagnosis becomes the whole identity

At Sandstone, we intentionally focus on the whole person—strengths, context, and individuality—because empathy grows when people feel seen.

3. Environment Can Slowly Normalize Harm

One of the most uncomfortable truths from this research is that harmful behavior often doesn’t start abruptly. It builds gradually.

Small boundary crossings become routine. Silence becomes consent. Discomfort gets dismissed.

In therapy, we often help clients recognize these patterns—not to assign blame, but to restore agency and choice.

The Power of Speaking Up

One of the most meaningful moments in this story comes from a person outside the experiment. Christina Maslach, a visiting graduate student, witnessed what was happening and spoke up. Her concern ultimately led to the experiment ending early.

Her role reminds us that:

• Outside perspectives matter
• Speaking up can interrupt harmful systems
• Change often begins with one person naming what feels wrong

This is something we actively encourage—in families, schools, and organizations.

Bringing This Home

The Stanford Prison Experiment reminds us that:

• Behavior is shaped by context
• Most people are not “bad,” but many are overwhelmed by systems
• Awareness and support are powerful protective factors

At Sandstone Psychology, our goal is to help individuals and families better understand the environments they’re navigating—and to build skills, insight, and support that allow them to respond with intention rather than pressure.

A Gentle Question to Reflect On

If you found yourself in a role with more power—or less—than you’re used to, how might it shape your behavior?

And who helps you stay grounded in your values when the environment pulls you away from them?

If these questions resonate, you’re not alone—and support can make a meaningful difference.
