Some people intuitively think multiple plys ahead.

Most people see only one ply.

When a mult-ply peron sees how the first ply lines up with later plys they get extremely excited in a way people who only see the first ply get confused by "this looks basically like the other one… what am I missing?"

Also, a great one ply idea that runs into a wall on the second ply they just can't even pretend to be excited by.

So people think they're not being a team player, because the idea is great on a single ply but bad in a way most people can't see.

The multiply thinkers are sensing a dimension that other people can't see.
