तयोः अर्थो न वेति अनर्थो न वेति अर्थोऽनर्थ इति अनर्थोऽर्थ इति संशयः ॥ कZ_०९.७.०८ ॥
tayoḥ artho na veti anartho na veti artho'nartha iti anartho'rtha iti saṃśayaḥ
Uncertainty (saṃśaya) is when, regarding the two (gain and harm), one judges: “perhaps it is not a gain”, “perhaps it is not a harm”, “the gain may turn into harm”, or “the harm may turn into gain”.
Policy outcomes can flip signs over time; uncertainty includes misclassification (gain vs harm) and reversals (gain→harm, harm→gain).
