As for most attempts to classify people, it should be strongly stated that any single human would fits several quadrants depending on the subject, the phase in their life they are in, or even the mood of the day.

I read this two dimensional presentation only as device to discuss a theoretical point, and not something that could have any practicality.

In particular, I think a lot of people switch from the "sheep" quadrant and the "naughty ones" pretty freely. They'll want to obey rules until they hit one that they feel doesnt' make sense and/or needs to be broken, and ideally will get back to being "Sheep" once it doesn't make sense to be a "naughty one" anymore (i.e. rules have changed, or better, they changed the rule)

That's also a reason why I see places like startup hubs where people consciously behave in unconventional ways (= be jerks, most of the time) to feel like they're "naughty ones" shouldn't be lauded, and being indepdendent minded should be balanced with benefits to the surrounding people or society (if you break big rules, it should have a big payoff for everyone)

PS: I find wording it as "sheep" to be unneedingly pejorative towards people who just don't break the rules and let others live their own life. In other classifications it would be "lawful neutral" for instance.
