The Obvious Perspective

This is something I think we fail at. We can judge or rationalize peoples arguments, but really knowing someones perspective is tough. I was thinking about this with respect to meta-cognition, thinking about how to think about something. But what about thinking about how another person thinks about how they can think about how they would think about a problem? I think this the most coveted skill in teaching.

So thinking about that this morning, I came up with this problem that is puzzling, but amusing it its simple solution. With any such problem it is about perspective.
Which of these sequences is not like the other?

a) 1243
b) 2314
c) 2341
d) 3421
e) 4132

Hint #0: (The pattern between the four other numbers should be easily describable in one common word that would logically reveal the answer to a reasonably clever person.)

Hint #1: ( Each block is a sequence of digits, not a 4 digit number. )
If nobody comes up with a solution by the end of the day, I will post a hint.
