The chart of basic personality types just put forth is of course only half the story! While some of the words used in the personality types chart are completely without "good" or "bad" bias, a few of them are. So for some words, adjustments are required to see the complete picture. Because... some personality types are organizers, and some are known for being hopelessly disorganized. Some types are great empathizers, some are downright cruel. Some have the vision of a developer, some are lost in a fog. Some are as brilliant as an inventor, some are as dumb as a bag of hammers.
But whether smart or stupid, the brain and mind are still the focus. Whether visionary or lost in a fog, the eyes and perception are still the focus. So to know the opposite five types of this system, you could just add a De- or a Dis- or an Anti- or an Un- or a Non- or some other negating prefix in front of each of the words offered here, and create a whole other chart of "bad" types.
But whether subjectively "good" or subjectively "bad," the five basic "Types" of this system remain:
1/9 - Cerebral (Clever, Encyclopedic type... or not... Confused, Idiotic)
2/8 - Perceptual (Poetic, Enthusiastic type... or not... Prosaic, Melancholic)
3/7 - Sensorial (Sensitive, Sympathetic type... or not... Severe, Sarcastic)
4/6 - Visceral (Valorous, Charismatic type... or not... Vulnerable, Sophistic)
5 - Elemental (Eloquent, Diplomatic type... or not... Equivocal, Anarchistic)
If you don't like any of the names on these charts, you could try picking a more abstract name for each type from one of the many keyword charts offered on this site that attempt to describe the fundamental essence of existence with words. Or... you might use one of the words being used to describe the tarot icons of The Numerical Tarot Deck. To see how those tarot icons relate to these five basic "Types" try examining the results page of The All Things Are Numbers Personality Type Indicator!
If you do chose to compare these five "Types" to other charts and diagrams on this site, take careful notice of the numerous binary subdivisions that make up the matrix of The Numerical Tarot deck. Notice how the spectrum of social involvement just described, coincides with the analogies made elsewhere on this site between our model of existence, and that of an atom - with negative outsides and positive insides. Or the Planetary model, with intangible limits and atmosphere on the outside and tangible surface and mass on the inside. Or the resulting suit arrangement of:
4/6 = Addition (Coins)
3/7 = Multiplication (Cups)
2/8 = Subtraction (Staves)
1/9 = Division (Swords)
These analogies, combined with the spectrum of social involvement just described, might hint to the idea that some types may be more devoted to a collective (the positive mass of the model), while some may exhibit more independence (the negative limits of the model). If this design is translated into the perspective of our personality types it could cause the cooperative attitude of the 1/9 and 2/8 types to be more exclusive (i.e. operating and functioning on their own terms, exclusive of the influence of others), and the cooperative attitude of the 3/7 and 4/6 types to be more inclusive (i.e. operating and functioning on mutually agreed terms, inclusive of the influence of others).
Another pattern that might be helpful to superimpose over this chart would be the Geometric and Dimensional models. In each of those models we see yet another binary subdivision of opposites on a matrix that might influence the perspective of each of our types. In this case, we see a pattern of alternation from one number to the next as active steps of progress are separated with passive steps of progress. If this design is translated into the perspective of our personality types it could cause the 1/9 and 3/7 types to communicate in ways that are less direct, passive or abstract, and the 2/8 and 4/6 types to communicate in ways that are more direct, active or absolute.
Of course, you don't really nead to superimpose all these models to see the resulting pattern, the operations of mathematics that are used as suit signs for The Numerical Tarot are enough - two negatives (divisioin, subtraction), two positives (multiplication, addition), each one with a somewhat abstract operation (division, multiplication), each one with a more absolute operation (subtraction, addition).
