Though LNH is often touted as preventing voters from being hurt by indicating later preferences, in truth it only prevents voters from hurting a candidate they ranked higher when they do this. <ref>{{Cite web|url=https://www.electionscience.org/library/later-no-harm-criterion/|title=Later-No-Harm Criterion|last=|first=|date=|website=The Center for Election Science|language=en-US|url-status=live|archive-url=|archive-date=|access-date=2020-05-14|quote=So those two voters get a better result by limiting the number of candidates they rank. That is, sincerely ranking candidates after W hurt them. It’s almost as though we need to have two different criteria: voter later-no-harm, and candidate later-no-harm. The “later-no-harm” criterion is actually the latter. IRV ensures that a voter can’t harm a candidate by ranking additional less preferred candidates further down the list. But voters can still hurt themselves by doing so.}}</ref> It is not known which voting methods, if any, pass the generalized form of LNH.
