Ever wondered how we sort stuff in our heads? It turns out, we have a special way of organizing materials. We can see and compare materials easily, which is super important for daily life. But how do we do it?

Researchers dug deep into this question. They created a huge collection of 200 different materials and 600 photos. Then, they got people to compare these materials in a specific way. This was done by asking 1. 87 million times for people to pick the most similar material from three options. This process was used to figure out what makes materials similar in our minds.

The results were surprising. They found that we use 36 different ways to think about materials. Some of these are easy to see, like how grainy or blue something is. Others are more about what we know, like if something is a mineral or if it's gooey. These 36 ways are really reliable and easy to understand. This means we all pretty much see and sort materials in the same way.

This discovery is a big deal. It helps us understand how we make sense of the world around us. It also opens up new ways to think about how we design and use materials in the future.

But here's something to think about. Just because we all sort materials in similar ways, doesn't mean we all see them the same. Our experiences and knowledge can change how we think about stuff. So, while this research gives us a good starting point, it's important to remember that our perceptions are unique.
