In Gulenko's book, he criticizes the "logical positivist" approach to socionics. I am not sure what he means by this, but I suspect he means taking a person's conscious preferences and opinions on society at face value, for example someone with collectivistic views might be put into beta without looking at the deeper aspects of the person's psyche.
Gulenko and his school remind typologists that a person's conscious perception of themselves is not always in line with thee way they perceive their type. I agree with this, but I also think Gulnko goes too far in placing an emphasis on subconscious and automatic processes such as dreams, eye movement, emotional reactions, when trying to determine people's types. Type is seen almost as an automatic process, whereas DCNH subtype is how he justifies people's perception of themslves. DCNH is a layer above the type, a more conscious, deliberate effort at being something.
While I agree that sometimes people's self-perception is wrong, I also don't think the way type manifests, especially quadra values and one's attitudes towards them, is a solely automatic process. Often it is conscious and manifests itself through group conflicts and how one expresses one's values in groups of people. DCNH can amplify certain things, such as rebellion and independance in C subtypes, but that rebellion and indepenance is always within the confines of one's type (as Gulenko himself writes in his book). An LSI-C would still behave as a hive mind in a group and even enjoy it, albeit perhaps they would be attracted to groups which are less norm abiding, than say, N subtypes.
Quadra impacts one's behavior in a group and thus how one sees oneself, not simply DCNH.
