When we give someone a Socionics type, we type them according to a system of fixed cognitive traits.

When we observe that the typed person diverges from the type we gave them in thought or action, we must develop an explanation for the divergence.

Socionics is a system of fixed cognitive traits. Thus, our explanation for divergence must conflict with the Socionics typing.

Therefore, when we hold on to the Socionics typing and our explanation for divergence, we possess conflicting beliefs.

Conflicting beliefs cause cognitive dissonance, or mental discomfort caused by maintaining contradictory thoughts.

Thus, attachment to Socionics causes discomfort because Socionics is a system of fixed cognitive traits that fails to explain divergence in thought or action.
