Let’s suppose you have a box. Ideally this is no mere supposition but you actually have a box nearby right now. If you don’t, you’ve surely had one at some point, so in that case we’ll talk about that box.

Boxes are made for storing things. You can put all sorts of things inside your box. You could even put another box inside it.

And you needn’t stop there. Another box can go inside your boxed box, or you could even put multiple boxes alongside each other inside the original box. All manner of boxes can fit inside your box, each holding myriad boxes of its own.

Presented with this infinite cascade of boxed boxes, the probability of any individual box being the original container is vanishingly small. And looking at these odds, well, who’s to say your box is really the enclosing box at all, and not just another box inside an even greater box? Your box is almost certainly boxed within another, containing not only your box but you alongside it. From simple probability, it’s clear that you (and I!) are inside a box right now.

Suffice to say, always be wary of anyone that grants particular significance to or is otherwise ‘convinced’ by the simulation hypothesis.
