I have been playing around with this test, at first I got RCUEI
atheist/agnostic tendencies, unconcerned with public image, lower energy level, does not value tradition, avoidant, does not put the welfare of others above self, not punctual, unproductive, does not believe in human goodness, not easily moved to tears, seldom bothered by the suffering of strangers, insensitive to the needs of others, relaxed, quiet around strangers, tendency to believe only in self, people have trouble reading them but they don't care, late finishing work, acts without planning, withdrawn, rarely too busy, not a perfectionist, uncooperative, not prone to complimenting people, does not believe in life after death, avoids crowds, prefers unpredictable to organized, not passionate about bettering the world's condition, does not second guess self, able to control cravings, calm in crisis, ambivalent to the feelings of others, believes in the importance of art, dislikes small talk, socially uncomfortable, private, not known for generosity, acts without consulting others, hard to get to know, not easily frustrated, interested in intellectual pursuits, not open about feelings, loner, asks many questions, open to change, influenced more by self than others, bored at work
Some of the traits do match me, but I was also kind of offended by others, especially:
-unproductive,
-does not believe in human goodness,
-seldom bothered by the suffering of strangers,
-insensitive to the needs of others
-not passionate about bettering the world's condition
I am definitely not any of these so I went back and looked at the questions, some of them were kind of vague as to what they mean:
i.e.
I would rather please myself than others.
Who is “others”? Family, friends, people in need, or just random strangers?
I originally considered “others” to mean everybody, so I redid the test but this time with the questions about altruism, I defined “others” as people I actually care about. So this time I got:
RCUAI
avoidant, often late, patient, rarely prepared, non-aggressive, slow to judge others, withdrawn, unconcerned with image, relaxed, avoids crowds, easy going, not demanding, low maintenance, unambitious, not domineering, private, thinks before acting, concerned with the feelings of others, not wild and crazy, not controlling, does not like to show anger, hard to offend, dislikes the spotlight, uninterested in leading, not competitive, overly nice, not physically affectionate with most people, not bothered by disorder, level emotions, does not second guess self, agnostic/atheistic tendencies, not picky about food, not relationship obsessed, unproductive, unimposing, plain in appearance, disorganized, loner, lower energy level, very curious, uninterested in prestige/fame, not superficial, likes difficult reading material, does not get worked up about most things, fearless, flexible, trusting, does not stick to plans, easily distracted, interested in science, unconcerned that people have trouble reading them, a good loser, modest, not swayed by emotions
I am much more happy with the RCUAI traits than those of the RCUEI, I like to think they define me better, the only one I strongly disagreed with was “unambitious”. Too bad I had to fiddle with my answers to get a result that I felt matched me.

Oh also, on both times I got "Calm" as the primary type.
By the way, I am not sure how they determine the "atheistic/agnostic tendencies" trait, because none of the questions seem to be related to religious belief, the only one that really had anything directly to do with it was the one "I have many fears", which I answered that I don't.
