exactly how MAM is counted.<span style="mso-spacerun: yes;"> </span>For example, the link you sent me for Steve Seppley’s MAM counting tool has been very useful.<span style="mso-spacerun: yes;">
</span>With this tool, I have easily tested many other examples in an attempt to find a profile for which MAM elects a single-winner with a lower intensity of support from voters than the winner that would be elected by IRV.<span style="mso-spacerun: yes;">
</span>I did not find any such an example. <span style="mso-spacerun: yes;"> </span>For every example I tried, IRV and MAM elected the same winner.
<span style="mso-spacerun: yes;"> </span>However, since IRV (unlike MAM) does not consider all the voters’ preferences until the majority winner is discovered, I assume there must be examples of the two methods electing different winners with different intensities
of support.<span style="mso-spacerun: yes;"> </span>Still, I currently have no clear basis for continuing to suggest that IRV is more efficient at electing winners who have the highest available intensity of support from voters.</font></span></p>

respect to IRV except that MAM’s method of counting would be much more difficult for ordinary voters to understand?<span style="mso-spacerun: yes;">
</span>Also, do you agree that MJ (like MAM) has the advantage over IRV in electing a single-winner only after counting all the votes of each voter (i.e. the ‘grades’ that every voter has given to all of the candidates)?<span style="mso-spacerun: yes;">
</span>In addition, I see MJ’s method of counting these grades as being easier for ordinary citizens to understand than MAM’s method.<span style="mso-spacerun: yes;">
</span>Consequently, do you also prefer MJ to MAM?<span style="mso-spacerun: yes;">
</span>I also see MJ as more likely to prompt voters not to ‘rank’ the candidates but instead to ‘grade’ all of them honestly, i.e. to encourage more voters to grade or REJECT each candidate in the light of each of their own visions of what an EXCELLENT, VERY
GOOD, GOOD, ACCEPTABLE, or POOR candidate looks like.<span style="mso-spacerun: yes;">
</span>Electing the candidate with the highest ‘majority-grade’ also seems to give the least incentive to citizens to vote strategically.<span style="mso-spacerun: yes;">

I'll also note that MJ fails:<br>
<br>
- Participation: Failure means that a voter might make the outcome worse<br>
from his point of view by going to the polls. (Participation is<br>
notoriously hard to pass)<br>
<br>
- All-equal ballots irrelevance: you can have a voter show up and give<br>
every candidate the same rank, yet that changes the outcome. You'd<br>
expect that to pull every candidate equally in the direction of the<br>
grade that voter gave to every candidate, but that's not true.<br>

There are two ways to consider strategic incentive. Suppose you have a<br>
method whose benefit (additional utility) to a particular voter X is<br>
something like:<br>
<br>
</font></span><a href="http://www.wolframalpha.com/input/?i=ln%2820x%2B1%29+from+0+to+0.5"><span style="color: blue; font-size: 12pt; mso-ascii-font-family: Calibri; mso-fareast-font-family: "Times New Roman"; mso-hansi-font-family: Calibri; mso-bidi-font-family: "Times New Roman";"><font face="Calibri">http://www.wolframalpha.com/input/?i=ln%2820x%2B1%29+from+0+to+0.5</font></span></a><span style="color: black; font-size: 12pt; mso-ascii-font-family: Calibri; mso-fareast-font-family: "Times New Roman"; mso-hansi-font-family: Calibri; mso-bidi-font-family: "Times New Roman";"><br>
<font face="Calibri"><br>
where the x axis is the size of the strategizing coalition X is part of,<br>
when everybody not in the coalition votes honestly.<br>
<br>
It's clear that no matter the size of X's group, X has an incentive to<br>
strategize. A rational voter will clearly always strategize.<br>
<br>
Now suppose the utility given to X is more like:<br>
<br>
</font></span><a href="http://www.wolframalpha.com/input/?i=ln%2820x%2B1%29+*+%28-SquareWave%5b1.2*sqrt%28x%29%5d+%2B+1%29%2F2+from+0+to+0.5"><span style="color: blue; font-size: 12pt; mso-ascii-font-family: Calibri; mso-fareast-font-family: "Times New Roman"; mso-hansi-font-family: Calibri; mso-bidi-font-family: "Times New Roman";"><font face="Calibri">http://www.wolframalpha.com/input/?i=ln%2820x%2B1%29+*+%28-SquareWave[1.2*sqrt%28x%29]+%2B+1%29%2F2+from+0+to+0.5</font></span></a><span style="color: black; font-size: 12pt; mso-ascii-font-family: Calibri; mso-fareast-font-family: "Times New Roman"; mso-hansi-font-family: Calibri; mso-bidi-font-family: "Times New Roman";"><br>
<font face="Calibri"><br>
i.e. there's a hard threshold before which strategy has absolutely no<br>
effect, positive or negative.<br>
<br>
A rational voter would still always strategize because there's no actual<br>
harm to doing so, and if enough voters aligned with his candidate think<br>
the way he does, he'll benefit. So it's a chance of getting something<br>
better with no risk, and a rational voter would take that.<br>
<br>
However, it seems unintuitive to me that a real voter would do so.<br>
