Three Psychology Experiments That Changed How I Live
Growth Mindset Psychology: The Science of Self-Improvement
Cathedral Effect: ceilings and creativity
Sam describes the cathedral effect: high ceilings boost expansive creative thinking; low ceilings aid focused tasks.
Most self-improvement assumes the problem lives inside you. But what if you've been looking in the wrong place?
There's something worth sitting with in the idea that your physical surroundings are already making decisions about how you think — before you've consciously made any. The shape of a room. Whether your body is moving or still. How many open tabs are silently competing for your attention. These aren't peripheral details. They're the architecture of your mental life. This episode revisits three environmental psychology findings that quietly reframe what it actually means to improve yourself — not as a project of relentless internal effort, but as something closer to intelligent design. You are, in a real sense, the product of your environment. The question is whether you're designing it or just inheriting it.
