Ranked by relevance and common usage.
Keep "inconsistency" when the sentence already sounds natural, when a synonym would add unintended emphasis, or when readers need the most familiar wording. A synonym should clarify or sharpen the message, not simply make the sentence look more varied.
If two options seem close, choose the one that best matches the audience and purpose of the sentence.
Choose a synonym only if it keeps the core idea of "inconsistency" intact in the sentence you are editing.
Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.
Read the full sentence after the swap. Keep the synonym only when the sentence becomes clearer or more precise.
Review note: Synonym lists are ranked with lexical data and reviewed for practical writing value. Use the comparison notes, sentence evidence, and source labels together; a high-ranking synonym can still be wrong when the audience, register, or grammar changes.
After choosing a replacement for "inconsistency", read the sentence once for meaning and once for rhythm. The best synonym should feel natural in the full sentence, not only accurate in a word list.
If the synonym makes the sentence slower, vaguer, or more dramatic than intended, keep "inconsistency" or choose a simpler alternative from the closest-match group.
OpenGloss and ConceptNet supply richer edges like generalizations, collocations, and derivations.

It is much to be wished that slavery may be abolished. The honour of the States, as well as justice and humanity, in my opinion, loudly call upon them to emancipate these unhappy people. To contend for our own liberty, and to deny that blessing to others, involves an inconsistency not to be excused.

I find it interesting that you've argued so hard for drastic reduction of the number of names in sentences as a means of preventing near-duplicates, and yet you're arguing for intentionally adding another kind of near-duplicates. You should think about that inconsistency.

It was a strange inconsistency, but never till then had I been so much struck with the worthless and frivolous life of society. Never till then did I feel the deep and eternal debt of gratitude that human nature owes to those who assert its higher influence; who feel their generous activity stirred by a thrice noble emulation; who appeal from the present to the future, and redeem their kind, by shewing of how much that is good and great ambition and genius are capable.
