'''Zero-Info LNHe (ZLNHe):'''
{{definition|In a 0-info election, voting above bottom one or more of some certain set of candidates shouldn't decrease the probability that the winner will come from that set, as compared to voting them all at bottom.}}

LNHe is relevant to bottom-end strategy. For example, many rank methods that fail LNHe have bottom-end strategy that calls for ranking unacceptable candidates in reverse order of winnability. A method that meets LNHe doesn't have such a strategy-need. LNHe-complying methods don't need bottom-end strategy.
Some methods that don't strictly meet LNHe can meet ZLNHe and maybe Strong ZLNHe. For example,
