Anyone interested in MBTI, should definitely take a look at Socionics. A few weeks ago I finally decided to give Socionics a chance and it gave me a better understanding about myself than MBTI did. The types in Socionics are imo portayed more realistc and less sugarcoating.
@Lion If you are an Infj in MBTI you are either an Infp or Infj in socionics, probably Infp. So if you are interested…

I recommend that you read the type descriptions of Gulenko, he’s regarded as one of the leading figures of Socionics. The other descriptions are good as well though, it’s just that there are so many.
All in all I think Socionics is superior to MBTI and explains some holes that the MBTI theory has. The only downside is that it’s not as polished and the community is a lot smaller. If you are interested I could link you some information about Model A, this helped me a lot.
