I was once interested in mbti as well. I couldn't see past it just like you two don't.
I can certainly see past it, I don't see it as being something like holy scripture. There are plenty of exceptions, and everyone as an individual is different, but based on broad generalizations, I believe it is good at determining in general what kind of a person you are. It's nothing set in stone. I know people who got one result and I completely disagreed with it. But you are right, you need to be honest with the answers. A lot of times with that test and others as well, people will tend to answer the way that they
wish to be, or want to be, rather than what they really are. I have accepted who I am, and was able to answer the questions honestly. I have read through almost 1ll 16 personality types from a few different sources, and like I said, for me at least, my description as me being an INFP is I would say 80-90% accurate. I do share some characterstics of some other types. But I can admit without a doubt that for one, I am much more introverted than extroverted - by far. I like my alone time. I like going out at times, it makes me feel refreshed, but I gain energy by being alone. When I trip, I like to be alone, or with one close friend. I prefer small close groups of friends rather than many acquaintences. I don't like being in the middle of large groups of people. I am shy around meeting new people usually, except in certain situations. I am an introvert.
I do tend to overthink and overanalyze things and worry about future possibilities, and I enjoy theorizing about things and fantasizing about alternate realities, living in my imagination rather than being practical, down-to-earth, straight to the point, and typically tend to overlook common sense more than I can say I'd like to. Though lately, I have been practicing keeping myself in the present, rather than overthinking, since I found I am more at peace that way when I am in control of my thoughts. Meditation and heavy weight-lifting, believe it or not (because of the intense focus and concentration used), have helped.
I am sensitive. I am emotional. I tend to do things and make decisions that make people feel better rather than always making the logical choice. Though as I've gotten older I have tried to create more of a balance, and not let my emotions get the best of me. I try to see things more objectively, though naturally I have always been more subjective and focused on my deep inner world of emotion, which now I see as letting my ego get the best of me - unintentional selfishness in a sense. Though I''m trying, I am a natural feeler and tend to do what "feels" right for me, rather than always making logical decisions - for example, leaving a secure job with a good salary to work my way around the world because it just feels right to me, though logically, it may not be the greatest decision in many people's eyes.
I am a type B personality. I am very laid-back. I am indecisive. I am open-minded and hate coming to definite conclusions about things. I try to perceive things openly and look at things from all points of view, without allowing myself to come to any definite conclusions. I am a perceiver, and do not judge without undue cause. Politically I'm libertarian, but always can see any issue from both sides of the same fence.
I do like travel, spontaneity, and new experiences. I don't like routine, I go against the norm, I have ideals that I will usually stick to, values I live my life by, and don't give in easily to others wants of me if it doesn't feel right. I am a thinker, an artist, a traveler, an idealist, and a people-person that enjoys helping others, especially on a one-by-one basis. Sometimes, actually often, my thoughts and feelings get the better of me, and I find myself looking to take a break from it all with some sort of escape drug. Other times, I choose to try and face them head-on with a mind-expanding drug - like LSD, which I think is only dangerous if one allows it and gives it the room to be dangerous. So while mbti may not be perfect, for me, it was accurate and has in my opinion at least a little more merit than you seem to be willing to give it.
But hey, were all different, and that's all there really is to it. Therefore, LSD would effect me completely different than someone else, but saying it is dangerous for all - period, seems inaccurate, given how my individual personality which I just described would be uniquely affected by it.
