Summary

Picture this. You're scrolling late at night and a reel pops up advertising a seemingly magical wellness product with some scientific-sounding marketing language. Do you stick around and maybe even believe it? Or do you scroll away? In this episode, Shoshana explores the mind, and how perception affects it. She shares two talks about how different people can experience reality in wildly different ways. First, Alex Rosenthal shares how having aphantasia prevents him from generating mental images, then Susan G. Wardle dives into the science of perception and why some people see faces in places that don’t exist, like clouds and even potato chips.

That moment of what if this is real is what this episode is about.

0:45.0

Not the product, the moment.

0:47.7

And that's what caught my attention this week.

0:51.8

The brain doesn't just passively take reality in like a video camera.

0:56.0

It gets involved.

0:57.0

It fills in blanks.

0:58.0

It makes guesses.

1:00.0

Builds meaning.

1:01.0

And one of the things it's extraordinarily good at is recognizing a story that fits what we already want to believe.

1:09.0

When we're tired or in pain or just quietly worn down by the gap

1:13.9

between how we feel and how we want to feel, we become very good at hearing evidence where

there isn't any. Wellness marketing has learned to speak directly to that part of us.

1:25.8

At wellness clinics, in longevity circles, and all over social media, treatments get

pitched with a cool assurance.

1:33.8

Ad language borrows the texture of science without requiring any of the actual proof.
