"[Property A] vs. not so" BPs will be assigned keyword "allsorted" (left-BP509)--that is, they sort all relevant examples--unless there exist ambiguous border cases, unclear about whether they fit [Property A] or not.

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 usually possible to frame 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. "Not so" Bongard Problems with a positive-seeming property on the left and a negative-seeming property on the right are usually "left-narrow" (left-BP513) and not "right-narrow"(BP514).

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