Misidentifying Ones and Twos
This is not a common mistype, but does occur when a wing is mistaken for the dominant type. In other words, 1w2s can sometimes be confused with 2w1s, but confusion is far less likely with 1w9s (owing to their reserved and relatively unemotional demeanor) and 2w3s (owing to their outgoing, effusive demeanor). Gender can influence this mistyping as well. Women who are 1w2s tend to see themselves as 2w1s, and men who are 2w1s may see themselves as 1w2s.
Both types are serious, and conscience-driven, both like to feel that they are of service, and both can be very altruistic; however, their styles and motivations differ significantly. Ones try to transcend the personal in their dealings, appealing to principles and the evident "rightness" of their positions or suggestions. Twos are highly personal and see their service in personal terms. Ones defend their autonomy–they do not want people to interfere with them. Twos seek close connection and even merging. Ones are restrained in the expression of their positive feelings although they let people know when they are dissatisfied or irritated. Twos may have difficulty with hostile or angry feelings, but they are fairly unrestrained in expressing their positive feelings.
