Because the thing is, this is the thing that I find gives a real insight into the hard problem, is that a lot of people who are colorblind do not know that they are colorblind at

Sometimes ever, but often until later in life.

And that, I think, is very interesting.

That, I think, really demonstrates.

Because this is something that is testable.

This is something that you can recreate so that we can understand how it looks for different people who suffer from red-green colour blindness, for example.

And it's so fundamentally different to the experience of the rest of us.

And yet you can go through your life having conversations with people the entire time and never know that you were viewing the world in a fundamentally different way.

My brother-in-law is kind of blind and, um,

And so for Christmas one year, I made him a t-shirt where I did one of the, you know, the colorblind tests where you have all the dots and it's one color against the other.

So I made him one of those.

And in it, it says in a pattern that he couldn't read, F the colorblind.

I think he knew straight away that I was messing with him.

We have a sort of Christmas tradition in my family of where we get each other gifts that sort of play on the other people's absolute weaknesses.

It's quite an Irish thing.

Yeah, he got me a t-shirt once where I'd done a TV program where I had hosted Have I Got News For You in the UK and at one point I'd done air quotes and someone had made a joke about whether I really was a professor while I was hosting this program.

And so he got me a t-shirt of just a screenshot of me going air quotes and just saying professor in inverted commas as though to really call my credibility into question.

So, you know, it's sort of a, it's a running thing.

Yours is a much more PC version, or much more human-centric version.

To be clear, I'm not anti-colourblind people.
