Omission of the neutral

The omission of the neutral is a type of general cognitive distortion. It results from the absence, in the patient’s system of taxa, of the neutral taxon. It follows that the elements of the reference class which can objectively be defined as neutral with regard to a given duality A/Ā, are not taken into account by the patient.

The omission of the neutral sometimes plays an important role, notably when there is a gaussian distribution of the elements of the reference class, where the elements objectively corresponding to the neutral taxon are precisely those which are the most numerous.

The omission of the neutral is part of the general cognitive distortions, as well as the disqualification of one of the poles, the requalification in the other pole, the arbitrary focus, the minimization, the maximization.
