▲The definiton written below is the one that I had originally written and used. I liked it, but it led to the question of "What if the way of voting that optimizes your outcome without favorite-burial is some complicated, difficult-to-find strategy?". That question led me to my better definition, written above on this page. Some time ago, someone else, too, had written it, and a link to it is given at the bottom of this page, under a different name.
==Earlier Definition==
Line 45 ⟶ 28:
A voter optimizes the outcome (from his/her own perspective) if his vote causes the election of the best possible candidate that can be elected, based on his own preferences, given all the votes cast by other voters.
'''Earlier FBC definition:'''
<em>For any voter who has a unique favorite, there should be no possible set of votes cast by the other voters such that the voter can optimize the outcome (from his own perspective) only by voting someone over his favorite.</em>
Line 58 ⟶ 41:
Election methods that meet this criterion provide no incentive for voters to betray their favorite candidate by voting another candidate over him or her.
An interpretation of this criterion applied to votes as cast is the [[Sincere Favorite criterion]].
