"BONGARD HELL."
This the flipped version of BP793 but using only images of Bongard Problems with solution "__ half more black/less white than other half versus vice versa," that all use rotated, reflected, and inverted versions of the same examples. |

COMMENTS

Left: the left hand side is enough to communicate the answer; the left pattern can be seen without the counterexamples on the right.
Right: the right hand side is enough to communicate the answer; the right pattern can be seen without counterexamples on the left.
Flipping a BP will switch its sorting.
The following is taken from the comments on page BP513 (keyword left-narrow):
Call a pattern "narrow" if it is likely to be noticed in a collection of examples, without any counterexamples provided.
A collection of triangles will be recognized as such; "triangles" is a narrow pattern. A collection of non-triangular shapes will just be seen as "shapes"; "not triangles" is not narrow.
Narrow patterns tend to be phrased positively ("is [property]"), while non-narrow patterns opposite narrow patterns tend to be phrased negatively ("is not [property]"). |

A similar, but different, solution is "center of mass is on the left half vs. center of mass is on the right half." |
