The Shala Daily

Students were told they had smart rats. Or dumb ones. The rats, of course, had no idea. In a classic experiment by Robert Rosenthal and Kermit Fode, psychology students were handed lab animals and told some were “maze-bright” — bred for intelligence — while others were “maze-dull.” The labels were completely random. But the rats whose handlers expected brilliance actually performed better in the maze. The handlers’ beliefs, transmitted through some combination of touch, tone, and attention, changed what the rats could do.

Think about that for a second. These were rats. Running mazes. And still, human expectation found a way in.

🔬 What Travels Through Touch

The study wasn’t trying to prove that positive thinking works or that we should all just believe harder. It was exposing something more uncomfortable: our expectations leak. They move through us in ways we don’t control and often don’t notice. The students weren’t consciously treating the rats differently. They thought they were being neutral, objective, scientific. But their hands knew something their minds didn’t admit.

This matters in the yoga studio in ways that are both obvious and strange. A teacher’s quiet certainty that a student can find steadiness in a pose — or their doubt that the student will ever get it — doesn’t stay locked inside the teacher’s head. It travels. Through the quality of a hands-on adjustment. Through the pace and tone of instruction. Through what gets noticed and what gets ignored.

I’ve been on both sides of this. I’ve watched students bloom under a teacher’s relaxed confidence, and I’ve watched them shrink under impatience that was never spoken aloud. I’ve also been the teacher whose own anxiety made a room feel smaller, whose need for a student to “get it” created exactly the tension that prevented getting it.

🪞 The Mirror We Don’t Mean to Hold

Rosenthal and Fode’s work helped birth the double-blind study — the idea that if you really want to know what’s true, you have to design experiments so that no one involved knows who got the real treatment and who got the placebo. You have to assume that knowing will corrupt the data. Not because researchers are bad people, but because we’re human, and humans broadcast.

We can’t double-blind a yoga class. The teacher knows who the student is. The student knows what they’ve been told about themselves — by previous teachers, by their own inner voice, by a lifetime of messages about their body and what it can or can’t do. But we can get curious about what we’re transmitting. We can notice the difference between offering an adjustment that says “I’m here, you’re fine, let’s see what’s possible” and one that says “you’re doing it wrong and I’m fixing you.”

The same thing happens in our solo practice. The internal monologue isn’t neutral. When you step on the mat already convinced you’re tight, distracted, bad at this — your body listens. Not because you’re broken or because mindset is magic, but because expectation is information. It changes where you put your attention, how you breathe, whether you give yourself a second to find the shape or bail at the first sign of difficulty.

🧪 A Small Experiment

Try this with a practice partner if you have one. Decide who’ll be the “teacher” for five minutes. The teacher’s only job is to silently hold the idea that the other person is capable, curious, and fine exactly as they are. Not to praise or coach or fix — just to watch with that assumption running in the background. The student picks a simple pose or breathing pattern and does it while the teacher offers minimal, neutral guidance.

Then switch. Notice what changes. Not to prove anything, but to feel what it’s like to practice under different kinds of attention.

The point isn’t to become paranoid about your thoughts or to pretend you can control outcomes by believing hard enough. The point is that we’re always in relationship — with students, with our own bodies, with the space we’re in. And relationship means influence. We’re not neutral. We never were.
