Strategy-free criterion

I'm trying to work out how the strategy-free criterion actually relates to
strategy, because it just sounds like it means the majority-Condorcet
criterion ("if a candidate majority-beats every other, they have to win if
everyone is honest"). @Michael Ossipoff email9648742@gmail.com ?

We vote by secret ballot.  We have the right to vote for whomever we choose for whatever reasons we choose.  There is no way to stop people from voting in a manner that is nefarious.  Like for bigoted or for dishonest reasons.

The voting system must not be dependent on voters voting honestly.  We are partisans, not judges.  No voter can be prevented from voting insincerely, but we can try to disincentivize that.  We should not assume, or require in advance, that voters vote sincerely for the election method to work correctly.  We should expect them to vote in a manner that they rationally believe is in their best political interest.

That’s why CW,Plurality is naive. Offensive strategy will make it no better

Closed, isn’t “Strategy-Free Criterion” your new name for FBC.

It’s a very inaccurate name. FBC-complying methods aren’t strategy-free in
any sense.

But they’re free of any need for drastic defensive strategy
(favorite-burial or any defensive order-reversal).

You want strategy-free? The wv Condorcet methods, such as RP(wv) &

Some time ago, I wrote a criterion that I called Strategy-Free-Criterion
(SFC).

Is that what you were referring to?

It was about a circumstance in which wv Condorcet is strategy-free. At that
time, autodeterence hadn’t been considered.

SFC didn’t catch-on, & I haven’t heard mention of it lately, & so I don’t
know it’s definition. But wv Condorcet is strategy-free in a meaningful
sense.

Why are we having a public discussion about a voting method criterion
without anyone giving its definition, and with apparently most of the
participants in the discussion knowing nothing about it besides its name?

https://electowiki.org/wiki/Strategy-free_criterion

Thestrategy-free criterionis avoting system criterion
https://electowiki.org/wiki/Voting_system_criterionfor
evaluatingvoting systems https://electowiki.org/wiki/Voting_system.

 Definitions

A sincere vote is one with no falsified preferences or preferences
left unspecified when the election method allows them to be specified
(in addition to the preferences already specified).

One candidate is preferred over another candidate if, in a one-on-one
competition, more voters prefer the first candidate than prefer the
other candidate.

If one candidate is preferred over each of the other candidates, that
candidate is called "Condorcet candidate" or "Condorcet winner".

 Statement of criterion

 If a Condorcet candidate exists, and if a majority prefers this
 candidate to another candidate, then the other candidate should
 not win if that majority votes sincerely and no other voter
 falsifies any preferences.

In a ranked method, it is nearly equivalent to say:

 If more than half of the voters rank/x/above/y/, and there is no
 candidate/z/whom more than half of the voters rank above/x/,
 then/y/must not be elected.

I think this evolved into the Minimal Defense criterion, the "votes-only
version" of which says that if more than half the voters vote A over B
and B no higher than equal-bottom then B can't win.

Evidently, then,  SFC merely says that the candidate can’t win without
order-reversal, while Minimal-Defense says he can’t win at all if the
minimal defensive-strategy is used.

It seems to me that Eppley’s Minimal-Defense was the votes-only criterion
based on SDSC.

…& that SDSC was the original, preference-&-sincerity version.

I preferred preference-&-sincerity because of its universal applicability,
where votes-only had to stipulate a balloting.

OK, so SFC prevents offensive truncation from defeating the Condorcet
winner, while minimal defense provides a simple way to stop order-reversal?

Evidently, then,  SFC merely says that the candidate can’t win without
order-reversal, while Minimal-Defense says he can’t win at all if the
minimal defensive-strategy is used.

It seems to me that Eppley’s Minimal-Defense was the votes-only criterion
based on SDSC.

…& that SDSC was the original, preference-&-sincerity version.

I preferred preference-&-sincerity because of its universal applicability,
where votes-only had to stipulate a balloting.

https://electowiki.org/wiki/Strategy-free_criterion

The strategy-free criterion is a voting system criterion
https://electowiki.org/wiki/Voting_system_criterion for evaluating voting
systems https://electowiki.org/wiki/Voting_system.
Definitions

A sincere vote is one with no falsified preferences or preferences left
unspecified when the election method allows them to be specified (in
addition to the preferences already specified).

One candidate is preferred over another candidate if, in a one-on-one
competition, more voters prefer the first candidate than prefer the other
candidate.

If one candidate is preferred over each of the other candidates, that
candidate is called "Condorcet candidate" or "Condorcet winner".
Statement of criterion

If a Condorcet candidate exists, and if a majority prefers this candidate
to another candidate, then the other candidate should not win if that
majority votes sincerely and no other voter falsifies any preferences.

In a ranked method, it is nearly equivalent to say:

If more than half of the voters rank x above y, and there is no
candidate z whom more than half of the voters rank above x, then y must
not be elected.

I think this evolved into the Minimal Defense criterion, the "votes-only
version" of which says that if more than half the voters vote A over B and
B no higher than equal-bottom then B can't win.

Is that what you were referring to?

It was about a circumstance in which wv Condorcet is strategy-free. At
that time, autodeterence hadn’t been considered.

SFC didn’t catch-on, & I haven’t heard mention of it lately, & so I don’t
know it’s definition. But wv Condorcet is strategy-free in a meaningful
sense.

Ppwrote:

I'm trying to work out how the strategy-free criterion actually relates
to strategy, because it just sounds like it means the majority-Condorcet
criterion ("if a candidate majority-beats every other, they have to win if
everyone is honest"). @Michael Ossipoff ?

Closed, isn’t “Strategy-Free Criterion” your new name for FBC.

It’s a very inaccurate name. FBC-complying methods aren’t strategy-free
in any sense.

But they’re free of any need for drastic defensive strategy
(favorite-burial or any defensive order-reversal).

You want strategy-free? The wv Condorcet methods, such as RP(wv) &
MinMax(wv), are strategy-free in a meaningful sense…effectively free of
need for any defensive strategy…due to their autodeterence.
