Later-no-help criterion
open-in-new
<p>The later-no-help criterion (or LNHe, not to be confused with <a href="/facts/Later-no-harm_criterion/pWXycyIq">LNH</a>) is a <a href="/facts/Voting_system/e6zvx3Bo">voting system</a> criterion formulated by <a href="/facts/Douglas_Woodall/PG6PVYyW">Douglas Woodall</a>. The criterion is satisfied if, in any election, a voter giving an additional ranking or positive rating to a less-preferred candidate can not cause a more-preferred candidate to win. Voting systems that fail the later-no-help criterion are vulnerable to the <a href="/facts/Tactical_voting/5cGzDa0c">tactical voting</a> strategy called <a href="/facts/Tactical_voting/5cGzDa0c">mischief voting</a>, which can deny victory to a sincere <a href="/facts/Condorcet_winner/p1pKVX0k">Condorcet winner</a>. </p>
