I was in a car with my SLI and ILE friends (they didn't met each other before). For the entire trip my SLI friend kept very silent and inexpressive (usual business).

Later that day, when we were alone, my ILE friend started talking me about a book (he thinks) describes a lot of techniques to observe people and he said that my SLI friend:

* Is a very cold and calculating person.
* Is not to be trusted.
* Is probably a covert cheater.
* His lack of expression and reluctance to give away opinions about things reflects that he has "something to hide".

He obviously doesn't know anything about socionics. I believe such remarks would be a massive PoLR hit. How would you feel if a person said something like that about you?
