They can like, oh yeah, it's a bit like when you go to the opticians and they always say like, you know, do they look different?

Does it look the same?

And eventually you get to a point where you really can't tell whether...

one lens is different from another.

And you can just calibrate until those circles to you look the same.

But then in reality, they will now be different.

And so you can measure how different they are in reality as an objective measure of how strong that illusion is for you specifically.

And if we do that, then we can measure that for 40,000 people and we can sort of see how does it vary?

Is it sort of like there's an average effect and then some people experience it more strongly, some people experience it less strongly.

And that's what we see.

And we can play the same game with other kinds of illusions as well.

And bit by bit we can build up a picture of

of how perception works for that person.

And maybe this is stuff we're still working on.

We can ask other questions like,

Are there deeper things happening that explain correlations between different illusions?

Like if this circle illusion is strong for me and maybe that correlates with something else, like the color I see addressed.

So what's the common factor?

What's the organizing principle of our perception?

And we're also now looking at how perception changes as we get older.
