http://www.kisa.ca/personality/ <<--- take the test!
I took this personality test with a bunch of friends tonight and it is extremely accurate if you really take the time to think through the questions. The test doesn't take too long, i'd say about 10 minutes. Here's my results:
I - Introversion preferred to Extraversion
S - Sensing preferred to iNtuition
F - Feeling preferred to Thinking
J - Judgment preferred to Perception
Characteristics
Myers-Briggs description
According to Myers-Briggs, ISFJs are interested in maintaining order and harmony in every aspect of their lives. They are steadfast and meticulous in handling their responsibilities. Although quiet, they are people-oriented and very observant. Not only do they remember details about others, but they observe and respect others’ feelings. Friends and family are likely to describe them as thoughtful and trustworthy.
Keirsey description
According to Keirsey, ISFJs, or "Protector Guardians", are most concerned with taking care of people by keeping them safe and secure. They are modest caretakers who do not demand credit or thanks for their efforts. But while they are essentially very compassionate-and in fact exercise more patience in dealing with the disabled than perhaps any other type-their shyness with strangers can lead others to misread them as standoffish. Only among friends and family may this quiet type feel comfortable speaking freely. ISFJs are serious people with a strong work ethic, not inclined to self-indulgence. They believe in being meticulous and thrifty. They work well alone. While they may enjoy taking care of others, they do not enjoy giving orders.
You can also look at the role variant that goes along with your personality type. I found that mine was mostly accurate, though there were a few things that didn't really fit at all. Here's mine:
Overview
Protectors are observant, cooperative, informative, and attentive. They are greatly concerned with the security of others and they often find assisting the downtrodden or people with disabilities to be satisfying. Protectors also find personal fulfillment in insuring the safety of others and may be attracted to jobs that enable them to do this as medical practitioners or insurance agents. Protectors are also quite skilled at executing routines and this enables them to be skillful in jobs that require conservation skills such as curators or police officers. Protectors are thorough, frugal and they abhor the squandering of material resources.
Protectors are comfortable working alone and they are often uncomfortable being in positions of authority. When they are in positions of authority, they often try to do everything themselves. Protectors have a very strong work ethic and this can lead them to be overworked. The least hedonistic of the role variants, Protectors are willing to complete jobs other role variants manage to avoid, especially if it enables them to help those in need.
Protectors often talk about daily life and every day concerns; however, they are not as sociable as other role variants. They tend to be talkative to only to a close circle of friends. Protectors' shyness with strangers can make them seem to be cold even though they are often warm and sympathetic. Protectors are often undervalued as their commitment to security and their economies are often taken for granted.
Protectors value traditional ways of doing things and are not interested in experimentation or speculation. They deeply value family history, heirlooms and property as well as cultural norms and traditions. Protectors firmly believe in the stability offered by credentials, titles, offices, birth and other forms of traditional authority. Protectors dislike situations where the rules are constantly changing.
