Bongard Problem with solution that can be naturally expressed as "___ vs. not so" vs. not so.

Left-sorted BPs have the keyword "notso" on the OEBP.

This meta Bongard Problem is about Bongard Problems featuring two rules that are conceptual opposites.

Sometimes both sides could be seen as the "not" side: consider, for example, two definitions of the same Bongard Problem, "shape has hole vs. does not" and "shape is not filled vs. is". It is possible (albeit perhaps unnatural) to phrase the solution either way when the left and right sides partition all possible relevant examples cleanly into two groups (see the "allsorted" keyword left-BP509).

When one property is "positive-seeming" and its opposite is "negative-seeming", it usually means the positive property would be recognized without counter-examples (e.g. a collection of triangles will be seen as such), while the negative property wouldn't be recognized without counter-examples (e.g. a collection of "non-triangle shapes" will just be interpreted as "shapes" unless triangles are shown opposite them).

BP513 (keyword "left-narrow") is about Bongard Problems whose left side can be recognized without the right side. When a "not so" Bongard Problems is "left-narrow" (left-BP513) and not "right-narrow"(BP514), that makes the property on the left seem positive and the property on the right seem negative.

The OEBP by convention has preferred the "positive-seeming" property (when there is one) to be on the left side.

All in all, the keyword "notso" should mean:

1) If the Bongard Problem is "narrow" on at least one side, then it is "left-narrow" (left-BP513).

2) The right side is the conceptual negation of the left side.

If a Bongard Problem's solution is "[Property A] vs. not so", the "not so" side is everything without [Property A] within some suitable context. A Bongard Problem "triangles vs. not so" might only include simple shapes as non-triangles; it need not include images of boats as non-triangles. It is not necessary for all the kitchen sink to be thrown on the "not so" side (although it is here, in BP876).

Contrast "viceversa" (left-BP1162).

"[Property A] vs. not so" BPs are often "allsorted" (left-BP509), meaning they sort all relevant examples--but not always, because sometimes there exist ambiguous border cases, unclear about whether they fit [Property A] or not.
