Most of the people on PerC just say "but the function order is the same?" and go with the j/p switch. They ignore all descriptions and mechanisms from socionics, blur elements into the MBTI counterparts as explanation, and use western resources, which base their sites on j/p switch being factual, to validate it in a self-perpetuating manner. They then use such to further spread this information. The wide majority of people on there talking about Socionics on there are rarely talking about actual Socionics. Most of the time, they're really just talking about what they themselves have observed and rationalized after the assumption j/p switch is true. I usually have no idea what they are talking about, because none of it is even remotely similar to any of the major socionics schools. Combine this with the fact that PerC has a population that is split between having MBTI types based on assessments such as Type-1 or kiersey, and the other half having "MBTI types" based upon them not knowing MBTI and derping through "functional analysis" to get it... And you really just have one giant cluster **** of information that is worthless. You're better off using the article that had Socionists measure peoples identification between the two systems' descriptions.
