I have to wonder if you understand the phenomenon of new arrivals arriving who all know each other in their own worlds. But that isn't the point.

You want us to figure out why these experiments do what they do. Without looking at individuals, or being completely centrist in our observations. Which means looking for commonalities.

Our common traits are our wings, our barcodes, and the fact that we are still here, within the barrier. You most certainly don't have barcodes, because you aren't being tracked like cattle.

That leaves the wings and the barrier as commonalities.
