Holists, either irredundant or redundant commit mistakes due to simple over-generalization (for example, that (β) always implies "Bushy Tail" which is true for only some subspecies) or systemic over-generalization to render the classification scheme more rational or symmetrical than it actually is (for example, falsely naming a subspecies "Bit QL" on the evidence that Q stands for "4-legged" and L stands for "Linear" together with the valid inference that a 4-legged linear creature exists.
A serialst is prone to list the subspecies by examining picture cards in Class A. If he is to be successful, he checks the relevance of the information entering his list by forming single predicate hypotheses.
