There was a lot that went into the Stockholder's voting twist. It actually didn't start out with anything to do with stocks or a business setting that was a flavor that was added on later.
One of the rounds that was always included in the bunch was something I called Trusted Weighted Vote. The more people trust you, the more your vote counts! I thought that was a really cool idea since all the other voting processes were like 1 person = 1 vote. And who wouldn't want to give the trusted cits more voting power??
Later on this was merged to the really cool idea of a shareholder's meeting at a company. People vote with stocks depending on what % of the company they own. There's a board of directors who manages it. (thought of including this in some way but ended up not doing it.) The first problem was what to call it... Wikipedia gives so many names. Should it be stockholder, stakeholder, or shareholder?
So that worked awesomely especially with the Union theme. For the record here were the #s of votes:
1. 501 stocks
2. 440 stocks
3. 400 stocks
4. 380 stocks
5. 360 stocks
6. 340 stocks
7. 320 stocks
8. 300 stocks
9. 260 stocks
10. 200 stocks
11. 100 stocks
A good bit of really interesting math went into figuring out these numbers. In previous essays I would just handwave over it but I actually want to go through this!
But let's start at the beginning of the twist cause that's kinda like the end.
So at the chat before I threw out ONE HUNDRED VOTES which got everyone excited haha. I hadn't really intended to like completely deceive y'all on that so much. What I was going for was that first I told you that you all had 2 votes, then I think that one person would get 100. The thing with the two votes and then the upgrade to a 100 was that it implied that the number of votes could change a lot. (and to further the logic, would change again as more people got more votes)
But that didn't really get through with the way I presented it and ended up kinda silly on my part. Another part which sucked was that that was 2 out of 4 days in the episode spent worrying about something that didn't come to fruition rather than spending that time strategizing about the possibilities with the real, interesting voting twist which was unfortunate. I wish y'all had more time to think about it.
So first I had you make up a trust list. For awhile it was going to be a Spy list - rank people who you thought were a Spy. Actually wait... before all this it might not have even been a trust or a spy list. I think I considered having a ranking based on a challenge, or a group decision, I'm not sure. Anyway, okay so before the game I was debating Spy List vs. Trust List. I had done Spy lists before and usually they affect the game a lot. I was thinking the spy list would affect things too much at this late point in the game and that's not what I really wanted. Plus, Borda count was going to be originally rank everyone, and that was going to give out tons of info too.
Spy list had it's advantages but I'm really glad I shifted it to trust list. It's kinda the same, kinda not, and has a little bit less of an impact which I liked.
So anyway usually with these things I tell you to rank everyone and I assign this unique, cool point system. But this time I wanted to try something different! I told you to rank your top three trusted and your bottom three trusted. I would then combine them to make a master list.
This may be a little mathy but stick with me haha I find this really interesting. Now most people when combining lists would just go like okay, ranked #1, gets 1 point, ranked #2 gets 2 points, #3 3 points and tally them all up. Person with least points overall is #1, second least #2, etc.
But these point values are so arbitrary. Why are we assigning a point value for second place that is double of first place, while assigning a point value for tenth place that is 10/9ths of 9th place? (10 points for 10th place, 9 points for 9th place). Why are the magnitudes that way and would the result end up changing if we did some other intuitive way, say ranking them 1, 2, 4, 8, 16 points?
Yes it would actually, it would change quite a bit! Each way you change it ends up in different results. So what's the best way to change it? How do you combine several lists into one master list?
Actually if anyone can point out a mathematically more efficient method I'd love to see it. I'm sure there is one for combining several lists into one master list. But here's what I thought. First, the 3 points, 2 points, 1 point system I just thought wouldn't work. Why is most trusted 3 times as valuable as 3rd more trusted? That seems a little high to me, I mean they are 3rd most trusted lol. It's a little weird to make the 1st most trusted worth 3 times as much as the 3rd most trusted, but make the 3rd most trusted only 1 point more than 4th and 5th most trusted.
But how much more valuable should most trusted be? I didn't know, but I wanted to find out. So here's what I did, I assigned variable point levels to your rankings.
1st most trusted: 'a' points
2nd most trusted: 'b' points
3rd most trusted: 'c' points
1st least trusted: '-a' points
2nd least trusted: '-b' points
3rd least trusted: '-c' points
definition: a > b > c
So rather than making a definitive point list, I decided to keep them variable. That way I could try out every different possible point list while I was comparing them. And if someone was always higher in every single point list than someone else, then they would be ranked higher for sure!
And then I tried to rank all of you on that which was tons of fun. Here's actually what y'all had:
So for Jenya, who got 3a + b - c, that would mean 3 people ranked her 1st most trusted, 1 person ranked her 2nd most trusted, and 1 person ranked her 3rd least trusted.
Jenya: 3a + b - c
Kirsten: 3b
Jason: 3a + 2b
Roxy: -3a + b
Khaled: -a - b - 2c
Boris: -2a - 2c
Pete: 2a + c
Tiberius: -a + b + 2c
Mirela: -a - 3b
Levi: b - 2c
Gretchen: -2a - 3b - 2c
Georgia: -4b + 2c
Okay so rank all of those into a list from greatest to least! That's the fun part haha.
To do that, I first started out with my definition a > b > c which is self-evident. I also found out I needed to add in other assumptions. For example, I added in that b + c > a. This means that the 'worth points' of you voting for 2nd most trusted and 3rd most trusted added together should be more than you voting for 1st most trusted. By the way, the 3, 2, 1 system does not meet this assumption since 2 + 1 = 3.
I'm not going to go through every single calculation haha but with these specific values it wasn't as difficult as it could be, which was nice. There's some quick things you notice with this list. First, some of the values like 2a + c are always going to be positive numbers, and some of the values like -4b + 2c are negative. (because b > c.) Turns out all of them are one or the other so you can divide it into two tiers which makes it easier. The top half only has four people and it's pretty straight forward to rank these:
3a + b - c
3b
3a + 2b
2a + c
for example let's look at 3a + b - c and 2a + c . Which is more?
3a + b - c > 2a + c because
---
a > c and b > c [definition]
a + b > c + c [adding the two]
a + b > 2c
2a + a + b > 2a + 2c [adding 2a to both sides]
2a + a + b - c > 2a + 2c - c [subtracting c from both sides]
---
3a + b - c > 2a + c [what we wanted to show]
The negative ones were a bit more fun cause some of them were pretty close. For example, I don't think it is immediately obvious how the rankings of these should go:
-a - 3b
-3a + b
-2a - 2c
- a - b - 2c
The way I did it was via comparison of all the expressions. If one equation is bigger than another and that another is bigger than a third, then the first one is bigger than the third one. By fitting them all in bigger or smaller than one another it all lines up.
Of course like I said these relations depend on what point system you end up using. You could change the order if you decided that a = 1000 b = 950 and c = 500 for example which fits all our current assumptions. You need to make a few more expression assumptions to rank them properly. The closest assumption I ended up making was between:
3a + 2c and 5b. Which is larger?
Maybe you could argue it either way. But my opinion is that the 'gap' between 1st and 2nd most trusted is slightly larger than the gap between 2nd and 3rd most trusted, or a - b > b - c . Why? Well think of it this way. Your absolute least trusted comes to mind right away. It takes a lot for that person to get the world's worst award. But now think about ranking a 9th least trusted and a 10th least trusted. It's kinda the same especially when there's so many people, it's hard to distinguish. The difference between 10th and 9th and maybe say, 5th and 4th is a different value there.
Following that logic to the end is how I got that the 'gap' between 1st and 2nd most trusted is slightly larger than the gap between 2nd and 3rd most trusted, or a - b > b - c .
Let's try and show that 3a + 2c > 5b using our new assumption.
---
a - b > b - c [assumed]
a + c > 2b [rearranging of terms]
2.5a + 2.5b > 5b [multiply by 2.5]
a > c [definition]
a - c > 0 [subtract c from both sides]
.5a - .5c > 0 [multiply by .5]
---
3a + 2c > 5b [add .5a - .5c > 0 to 2.5a + 2.5c > 5b]
So anyway, surprisingly, that all worked out! If you are in lala land with all these variables and would want an exact number system which fits all the criteria I decided upon, a simple one is:
a = 10 points for most trusted
b = 7 points for 2nd most trusted
c = 5 points for 3rd most trusted
which sounds fair I think.
Yeah so that's part one haha. We haven't even gotten to the actual vote part yet, which is the interesting part. Part two up soon!
