Each personality type has an inherent connection to the types on either side of it, known as wings. Usually, though not always, one or both of the wings influence the core personality. For example, an EIGHT with a SEVEN wing will be much more outgoing (a SEVEN characteristic) than an EIGHT with a NINE wing. But the core motivation and characteristics of the EIGHT stay the same. The habit of mind does not change, but here we can see that it may be expressed in a variety of ways. This begins to account for variations in personality.
