The heuristics are presented in the form of a two column table. The left column lists contradictions, which could be difficult to resolve. The right column suggests contradictions, with which substitute them so that to solve a problem.
|Difficult contradiction||Contradiction, which could turn out to be easier to resolve|
|A has to have property B and has to not have property B||A has to exist and has to not exist|
|The value of the object's characteristics X has to be Y and has to not be Y||The object has to have characteristics X and has to not have it|
|The value of X has to be Y so that Z happen and has to not be Y for a reason R||Z has to happen when the value of X is not Y and has to not happen|
|There has to be X so that there would be Y and there has to be no X so that there would be Z||There has to be Y when there is X and there has to be no Y when there is X|
