Left-sorted Bongard Problems have the keyword "dependence" on the OEBP.

"Dependence" Bongard Problems could be considered invariance Bongard Problems, where the relevant kind of transformation is swapping the example out for any other example that shares the relevant property.

This was created as an example of a Bongard Problem that could include an image of a Bongard Problem with the same solution as itself but could not include the very image of itself (appearing within itself fractally).

See also BP961, "appears on its own left side vs. appears on its own right side".

Bongard Problems sorted left have the keyword "seemslike" on the OEBP.

In a "seemslike" Bongard Problem, some relevant information is left out by the way objects are displayed. Solutions to "seemslike" BPs sound like "Seems like a ___ based on the information available vs. seems like a ___ based on the information available". The two sides are typically negations of one another (keyword notso).

Since there is information missing, examples can only be sorted assuming they appear in a way that hints psychologically at what they actually are (see help).

Although the rule sorting the underlying objects may be precise, the rule sorting the projections of the objects with lost information is fuzzy and subjective.

See also left-couldbe (and right-couldbe), concerning situations in which the information given may be enough to determine when examples fail to satisfy a rule but is never enough to determine when they do satisfy the rule ("could be ___ vs. clearly is not"). In contrast to "seemslike" Bongard Problems, left-couldbe Bongard Problems can be precise; both evidence of fitting right and absence of evidence of fitting right is clear-cut, so no psychologically helpful hints (help) are needed.
