INFP = ADD

This is taken from Born to Explore - What is ADD? Attention Deficit Disorder, or ADD/ADHD, is a psychological term applied to anyone who meets the DSM IV diagnostic criteria for impulsivity, hyperactivity and/or inattention. The diagnostic criteria are subjective and include behavior which might be caused by a wide variety of factors, ranging from brain defects to allergies to giftedness. ADD is really more of a description rather than a specific disease. However, there is a tendancy for people to over-simplify ADD and view it as a singular defect or disease. Not true!

There are two major types of ADD at this time (this aspect of ADD keeps evolving): ADD with hyperactivity (the traditional type of ADD, also known as ADHD) and ADD without hyperactivity ("inattentive" type).

One common misconception about ADD is that many people assume ADDers cannot pay attention. This is completely false. In fact, ADDers are known to "hyperfocus" on anything which captures their attention, to the point where it is difficult to get their attention. It is true, however, that a higher degree of interest is necessary before the ADDer can pay attention.

The MBTI types that are most likely to be diagnosed ADD are: INFP, ENFP, ENTP, and INTP. You might notice that they are all of the type xNxP. From ADD and Personality Type, Rachael Hawkins wrote that there is increasing evidence to suggest that NP personality types are overrepresented in the ADD/ADHD population. Most of life is SJ; great if you are SJ, OK if you are SP or NJ, really crap if you are NP. Some characteristics of NP's may include: procrastination, divergent thinking, many interests, scatter-brained, get bored easily with something that doesn't interest them, extremely focused with something that does interest them, daydream a lot... etc. (hmm, seem to describe me perfectly). Often, these are also the descriptions of ADD behaviour.
