Yeah, in regions where polls say people twnd to vote with 2 parties, Droop is Best, where people tend to vote with more parties use Hare.

So you could do Hare at local, district, and county level to encourage the creation and growth of parties, then at national level have Droop to encourage more likely majority.
Can you use STV and MMP as a combined system?
pfysche - 2 måneder siden
I cant find any example of such a system, but I dont see why you wouldnt be able to. Personally I would prefer a system with no parties and CPO-STV, but if we're gonna have parties then maybe a combination of MMP and CPO-STV could be neat.

I think that I prefer droop because a) it would be more successful in its implementation with less opposition i.e. larger parties may be marginally less averse to reverting to it and b) coalitions often cause governments who struggle to conclude politics. Obviously, I know that that makes me sound like every politician who's ever tried to retain their seat by bad-mouthing proportionally, but I do advocate proportional representation; it's just that as we saw in places like the Weimar Republic, coalitions often prevent strong governments, so at some point, representation must cease to go to its full extent. First past the post is horrifically undemocratic, but I think that hare STV would be slightly unsuccessfully. It's not of massive importance to me, though, and I'd be similarly satisfied with hare as with droop.

What if, instead of single transferable vote, it would he htv - half transferable vote. Where if it was to move onto the second option, it would only give half a vote. This would make the voters prefer to vote their first choice.
Tab - 4 måneder siden
Your vote being worth half when your first choice fails to be become a representative would incentivise them to vote for the parties more likely to win so they have more say, bloating up bigger parties at the expense of the party you actually want? Why do we need to give them more intensive for them to vote for their first choice in the first place, what's the intensive to not vote for the parties you want to win in the order your prefer?

Then I guess the question I have to ask is which situation is more likely to happen? I think I would still prefer droop because it seems to me like the first scenario is much more likely to happen than the second, but if I'm wrong on that, I would say hare then. Depends on which is more likely
No system of voting is perfect or absolutely perfectly representative, but you can get close. Additionally, it's important for a nation's constitution to protect the basic rights of people who are social minorities so that one election can't take that away.

Honestly, by my preference, i'd say Hare is slightly better. I'd rather my government be cooperative, having to work together to effectively govern instead of one party trying to force through everything on a slim majority. We're having that problem in the UK right now, and it ain't fun.

I guess if we want more parties in America we should use Hare. And give Hares the right to vote for consistency’s sake.
Sunny - År siden
With Hare, in the first example the wrong result occurs. In the second it favours coalitions and minority rule. That's one huge negative result and one mixed result that's up to personal philosophy
With Droop, in the first example the objectively more democratic result. In the second it favours a system where a party has control. In this second instance Droop allows for a government to occasionally be speedier in their actions and enacting laws and change/progress. So Droop has one good result and one result that leads to an expedient government, which is still a mixed result up to personal philosophy.
Seems Droop is the best option then

With over 300 million Americans, the question is how many seats should the House of Representatives have under STV, in total assuming most seats have between 5-7, with dense populations [like NYC] having 9 and sparsely populated areas [like Alaska] having 3.
Timothy T.
Timothy T. - År siden
There must be an interchangeable system that favors the most diversity amongst the populace within a reasonable degree. For example, if there are three major parties noted on the charts, there should be a representative from those parties.
However, the system should also allow for multiple seats to be occupied by the same party within reason. For example, there are five parties, but only three major parties are going to win. Then, the parties with the most representation (votes or what have you) should have more chairs to best represent that group.
In the event that there is an error in the system, there should be some sort of backup system to override broken results. For example, there is eight major parties for five seats, but everyone was the dumb and only voted for one person, somehow making an eight-way tie. Well, what to do? We could hold another election with those eight and mandate that everyone must vote two or more. This is certainly one option, but it is not the only one that could work.

I would use STV mixed with MMP, so I guess Hare would give more local minority representatives and more majority party representatives, whilst Droop would give more local majority representatives and more of the top members or minority parties. I don't know which would be better though.

Think about it like this: When you are electing one person the majority is 50% + 1 not 100%. Therefore electing 2 people should be 33% + 1, 3 should be 25% + 1, 4 should be 20% +1, 5 should be 16.66% + 1 ect.

I think when doing a system I would go for STV droop for reps and the same for pres. But once a law is about to be passed as in it has passed through legislation the people would get a final vote either yes or no. For that i’d do FTPT because you can only get a majority with 2 choices people who abstain don’t care which one so it doesn’t matter. And i think veto sucks.

This was invented actually before almost all modern constitutions were written, in 1819. I believe it was first used for entire legislators in the Republic of Ireland, I think it was used before that in the university constituencies in the UK parliament, the rest of the seats were allocated with people getting say 2 votes they could use out of 3 seat districts, sometimes 1 vote out of two candidates, also called the limited vote, and municipalities in the US used it a bit before the Republic of Ireland chose it. Australia followed for Senatorial elections in I think 1948. Update: Found the history.

Charle Gonzalez Mendoza It's better to be consistent and always use the same one. On the last example in the video, where hare had one of each as a rep, and droop had two monkeys and an owl: People will disagree on which one is the "fairer" option. Who will decide which one is fairer? Lynx supporters will say hare is fairer, but monkey supporters will say droop is fairer. It's better to have that cleared up beforehand.

Droop takes into account "wasted" or "exhausted" votes.
ChaosPod - 2 år siden
In other words, Total votes - (number of seats)*(Droop quota) < Droop quota
ChaosPod - 2 år siden
Here's a better math explanation as to why the Droop quota works: Let T = Total number of votes N = number of seats Therefore Droop quota = (T/(N+1) + 1) T - N (T/(N+1) + 1) = 1/(N+1) (T(N+1) - TN - N(N+1)) = 1/(N+1) (TN + T - TN - N^2 - N) = 1/(N+1) (T - N^2 - N) = T/(N+1) - N(N+1)/(N+1) = T/(N+1) - N < T/(N+1) + 1
ChaosPod - 2 år siden Well the formula is Integer (total valid poll / (seats + 1)) + 1 If the total number of seats is 4 then we would have Integer (100%/(4+1)) + 1 = 20% + 1 So (20% + 1) is our droop quota. We can see this is the minimum number to fill up 4 seats as 100% - 4 (20% + 1) = 100% - 80% - 4 = 20% - 4 < 20% + 1 which is our droop quota.
SPACKlick - 4 år siden
Basically it's how many votes you need to guarantee you can't be beaten. If you're electing one candidate from 100 votes, you could run the whole way through, eliminating people and moving second votes until you have 100 votes for the winner (Hare) Or you could divide by the number of votes by candidates +1 (100/(1+1)) = 50 plus 1 vote, 51. Once you have 51 votes, nobody can beat you so we may as well stop and say you won. Simlarly with 3 candidates from 100 votes, you could run the whole vote until everyone has 33 votes but it's clear that once a candidate has 26 votes they can't come 4th and so must win a seat.

@Robims "because it can just pair up with another party in the next period." that is not the strongest weapon in the arsenal of any coalied party... they can change coalitions IN THE MIDDLE of a term, demand a vote of no confidence and set up a new chancellor with one or two other partners as long as the numbers fit... that is how Helmut Schmidt lost his office to Helmut Kohl in 1982. It requires the numbers to be very obviously sufficient for a successful vote in advance though, else the bigger party might just call the bluff and think they would still win the vote of no confidence.
Fredrik Dunge
Fredrik Dunge - Måned siden
@Robims No it tends towards the parties close to the centre having more influence because they can turn to both sides to find allies to compromise with. Those parties then grow because they are parties which have the potential to lead the country. Personally I see that as a feature not a bug.
Robims - Måned siden

I am sorry. Perhaps I need to work on my explaining skills. I will restate. You said that they should compare the votes to the demographics to decide on whether they should choose droop or hare. I tried to point out that you can't know the demographics without the votes so there is nothing to compare.There is no way to know if the droop or hare method would be more "representative" because all you have are the votes. Perhaps we have a misunderstanding about what "demographics" means. What do you mean by that word? How would we compare it to the votes cast?
Kayne Randolph
Kayne Randolph - 4 år siden
I don't understand your point I'm afraid. The demographics are separate from the votes but if you choose to abstain then your forfeiting your ability to affect decisions. So then why would the demographics of people who chose to let other people do all the work matter? Are you talking about minors who can't vote yet that becomes a lot more complicated. Should we assume the parents demographics match the kids? Well that's going to be a problem for the gay son to the homophobic parents whom the government assumes is also homophobic. Do we prob these young people with questions that they haven't had the opportunity to explore and answer? That is a complicated gray area but by not forcing that responsibility onto people whom you have to fight in order to make them take a shower is better then making them make choices that they are woefully ill prepared for.

Would a system taking the midway between the the minimum quota calculations for both Hare and Droop work well as a way to stay proportioned effectively? For instance, if three candidates are needed from 100 people, Hare would state that 33 votes are needed to get a seat and Droop would state that 26 are needed to get a seat. The difference between the two requirements is 7.333 votes (using the remainder from Hare for accuracy). If that difference were split down the middle to ~3.8 or 4 after rounding up and set at 30 votes required to get a seat, how would that affect the likelihood of a larger or smaller party getting elected? Would it split it down the middle more or less? Or would something different happen? Or would a slippery slope situation occur where the medium itself is challenged in comparison to Hare or Droop and another medium is created that leans toward one side?

I don't understand the tigers vs gorillas election example. STV is about votes to the candidates, not to the parties. Can you please work it out with numbers?
Twentydragon - 4 år siden
My preference in the second example would come down to the total discrepancy between each party and their representation.
Under Hare:
Lynx is over-represented by 9⅓%.
Owl is over-represented by 8⅓%.
Monkey is under-represented by 18⅔%.
The total discrepancy for the Hare system is *36⅓%*.
Under Droop:
Lynx is not represented at all, so that's 24% right there.
Owl is over-represented by 8⅓%.
Monkey is over-represented by 15⅔%.
The total discrepancy under the Droop system is *48%*.
Hare's system is closer, so it wins.
Unless I'm missing something, I think this comparison might actually benefit a lot of STV systems.
Sion's Media
Sion's Media - 5 måneder siden
Well since it’s government over 50% is the same as 100%. With the vote a majority of people did not want Lynx or Owl, the same as a majority of people wanting Monkey. Under Hare: A majority of the government is Lynx and Owl, or a minority is Monkey. A majority is now a minority. Under Droop: A majority of government is Monkey, or a minority of government is Lynx or Owl. A majority is still a majority.

@Lucas Knapp Because over-representation implies, under-representation in the same amount, adding all differences will always be 0 (and indeed, Monkey is 17⅔% under-represented in the first case, I also double checked and the rest of the results are correct). As Nick said, dividing positive (or, the same, negative) misrepresentation by two might give a better estimate, which would give ~9% and 12% differences.
Lucas Knapp
Lucas Knapp - År siden
I think I would actually prefer looking at it through average discrepancy. Obviously, perfect representation would be zero, but any over-representation yields a positive and any under-representation yields a negative. So using the second example: Under Hare: Lynx = +9⅓%. Owl = +8⅓%. Monkey = -18⅔%. The average discrepancy for the Hare system would then be -⅓%. Under Droop: Lynx = -24% Owl = +8⅓%. Monkey = +15⅔%. The average discrepancy under the Droop system is 0%. Whichever system is closer to zero would be better, which in the above example would be Droop. And if for whatever reason both were the same distance from zero (ex. Hare = 1% and Droop = -1%), in my opinion the better one would be the system with a positive discrepancy. Because I feel that it's better for the "average party" to be over-represented than under-represented.
Nick Pallas Misailidis
@Twentydragon In that case would it not make sense to divide the misrepresentation by half? If it's +1% in favor of one party, it automatically means it's -1% for the other party. The absolute difference is 2%, but it's 1% of the people that is misrepresented.
Jackson DeStefano
Jackson DeStefano - 4 år siden
If you use Hare, it'll cause Small parties to win, and then they get noticed more, then they gain traction and become larger and larger until they become unfavored by Hare when a new small party or a former large party becomes favored. It's a cycle. While Droop will keep the large parties in place.
Gryffin - 3 måneder siden
It may be best to use Hare for some districts and Droop for others. Two-party districts should use Droop, Multi-party districts should use hare for representativeness. Generally, we should expand districts as needed to increase accurate representation (like giving that last district 4 seats.

Well, coalitions, duh. One party ruling by 51% is like a dictatorship for the 49%, and if this system is in place it is likely to stay that way because any vote on the matter will lead to ≈51% of the people voting to keep the system in place, and it isn't hard to imagine why.

Is the 100 still just a percentage in droop?
Pete Gast
Pete Gast - 4 år siden
In STV, the goal is to find the N candidates who get above a threshold. If the threshold were (total votes) / (N+1), then we could have a N+1 candidates all tied at that threshold. As long as the threshold is 1 + (total votes)/(N+1), no more than N candidates can reach it. Therefore, the Droop threshold is the smallest number of votes that ensure that no more than N candidates can reach the threshold.
Michael Ståhl
Michael Ståhl - 4 år siden
Although there is a big difference if the Droop quota is raised by 1% or 1 vote every time the number of votes is something else than 100. 1000 votes and three seats could mean you need either 260 votes for one seat or 251 votes for one seat depending on if the calculation deals with percentage or actual votes.
Rob749s - 4 år siden
@XandWacky Sorry, in the example it is votes AND percent, because it is 100 votes. It would be necessary to convert with any other number of votes. So for 1000 votes with 3 seats, the Hare quota would be 333 1/3 (33 1/3%), and the Droop quota would be 250 (25%).
Whion - 4 år siden
@Rob749s So if 1000 votes were put up, it'd be 1000. That' be heck for 3 seats (If you have 1000 voters, you'd probably have more seats).

So, in Canada we're currently debating alternatives to the first-past-the-post electoral system. We have 5 main parties that each send a representative to run for Prime Minister. Would a system like this work for that? Like, say a party needs 50% to win, so you cut out the loser, add the 2nd choices, and re-count?

+JuiceBoxWizard You are describing Alternative vote or Instant Runoff, see Grey's video on the subject and its problems. There are better ways to have single-winner elections, Schulze is probably the best, but its a bit complex and Grey doesn't have a video on it. STV, the topic of this video, can't be used for single-winner elections, only multiple-winner representative councils/parliaments/congresses/bodies.

Bradley Callaway
Bradley Callaway - År siden
@MrKcspot you can tell which one is more accurate via a mathematical percentage differential method between the actual votes and the formed government (there are actually a couple voting systems that work this way intentionally, where you just match voting percentage and the government as close as you can.) So the first example looks like this: Hare: (60-47) + (53-40) = 13 + 13 = 26 error Droop: (47-40 )+ (60-53) = 7+7= 14 error and the second example looks like this Hare: (33-24) + (33-25) + (51-33) = 9 + 8 + 18 = 35 error Droop: (24-0) + (33-25) + (67-51) = 24 + 8 + 16 = 48 error
icedragon769 - 4 år siden
+Brooks Gaming Proportionality isn't the point though. The point of STV is that a candidate gets exactly as many votes as they need to win. To allow overkill is to punish voters for supporting a popular candidate. The Hare method forces overkill. With three winners, as soon as a candidate gets more than 25% of the vote, they've won. If you total their votes all the way up to 33%, you're basically discarding the 8% of the total votes by assigning them to a candidate that already won, those people might as well not have voted.

+Brooks Gaming ho would you tell that? I think that it should be immediately recognizable to whom gets what method. hare should probably be used in more populated areas to more closely represent the population and droop should be used in less populated areas.

I understand Droop better than Hare, if Hare was used to fill one seat the quota would be 100%.

@ajuk1 At the time I wrote that response the Federal senate voting reforms had not passed. The STV hare is still being used by some states though.

@Gregg Cayman Australia are dumb, they also force you to fill the list in for all but one of the candidates, total shoe in for one of the major parties to get your vote.

To fill one seat, the threshold under Hare would be 100%. Under Droop, the threshold would be 50% + 1.

the question is WHAT HAPPENS if "nunber of seats" = "numbers of parties x 2" that would be an interesting variable to see
20quid - 4 år siden
+Ramiro Galletti The parties run multiple candidates. Since votes are redistributed if you win, and votes are redistributed if you are eliminated, there is no risk of two candidates dividing their supporters in half. In Ireland parties generally run one more candidate than the amount of seats they expect to win in that particular district.

"Do you favor coalitions? Or do you favor a slim majority having absolute control?" Yeah. Very impartial lol. (I agree with you)

Why not use something in the middle?
Ernie - 4 år siden
There really is no middle ground, even though you could change the math for the exact number of delegates needed, you could still often end up with the same 33-33-33 or 67-33 results, since only one seat if affected by the choice

I honestly would favor Hare in the latter instance. While yes, you do have a chance of being run by a minority, with the lack of known details, you don't know that to be true. How do you know that Owl and Lynx would work together better than say Lynx and Monkey? Using Hare would ensure a more collaborative government which would benefit all people in the end.

Jaco as programmer8 said, hare just better represents the populace. thats honestly my main concern.

Basically it comes down to due you favor the minority or the majority.

Technically Hare results in the least discrepancy in this case (36.5% vs 48%). So it does represent the population better than Droop

the main problem with hare is that it leaves a large amount of people backing a candidate they don't like

How about you calculate both the systems, and then look which one has the least percentage difference to go with that one for that specific election.
XBlueM0ndayX - 5 år siden
Personally, I think in the Monkey-Lynx-Owl scenario that the Hare result is better. Everyone who voted gets a representative, rather than 24% of the population being somewhat disenfranchised. Government is sort of a separate issue to the voting system, closely related but separate.

Seeing as Droop works better for ranges with larger numbers, and Hare better for smallranes, why not just have a rule saying ranges with 3 seats or less use Hare, 4 seats or more use droop?

General question:  Are there any governments that use Droop in a two party election and Hare in a three party or more election?

This is so strange... 
I have absolutely not the first clue what this video is about.  I find myself laughing at my puzzlement; I like being completely ignorant of something, at least for a moment.
Alas, once I look up the meaning of this seemingly nonsensical rant, it will become all too clear and that magical sense of novelty that has been transmuted into wonderment by my frantic imagination, sans some simple knowledge...will be gone forever.

3:00 Hare:
33% + 33% + 33% = 99% Owl should be 34%.

Only Droop ensures that an absolute majority of votes translates into an absolute majority of seats.

I think you underestimated your audience in not using droop in your STV explanation. A good way to explain the "n+1" issue that you avoided is thus:
everyone gets that to win a single member electorate with an absolute majority you need 50% of the vote. But actually 50% plus one vote, because it would be technically possible for two candidates to get 50% each.
You don't need 100% of the votes to get win a seat that returns one member. Apply that. To win a seat in an electorate/district/range/riding that returns two members, you need 1 third of the votes plus one vote. That's it. Votes divided by (number of seats plus one) plus one extra vote to avoid a tie. For a 5 member range, one sixth of the vote plus one. For a seven member range, one eighth of the vote plus one.
I think you could have explained it better than I have just there, and I think your audience would have for it.

In the last scenario, I think that hate is better because it is more representative of the population. However I can see how having no outright majority would be a problem

I don't understand the first example. Maybe this has already been discussed and I just missed it in the comments, but it seems the Hare would end the same as Droop. Percentage for Hare is 1/5=20. First seat goes goes to Tiger, subtract twenty for the win, assume all votes go to 2nd candidate, now it's 33-47. Second vote goes to Gorilla, now its 33-27. Both happen again, so now 13 Tiger, 7 Gorilla. Neither have enough to earn a spot so lowest (Gorilla) is dropped and Tiger gets the third seat, same as Droop. Is there something I'm missing?
Zuleamu - 5 år siden
@Nate Snyder @Zwerggoldhamster @Jim Smith It's true that with 5 candidates you will not get this imbalance. But with 6 candidates it can happen. Ex. 120 total votes, 2 parties with 1st party getting 31,30,2 votes for its candidates and second party 20,20,17 votes. ( Pulled from wikipedia Comparison of the Hare and Droop quotas Scenario 1 )

Remember, there's no perfect electoral method nor even an electoral system. You just have to adopt one or two (in case of parallel voting) which you think it will give you the kind of results you want. It's all about what kind of results you want or what you think is ideal to a state or to an organization.

Great video, but there's a real problem with saying "that's just a philosophical difference, I don't think there's a right answer," as if there were no right answers in philosophy. It would be one thing to say "that's a philosophical question which is outside the scope of this video," but it's big mistake to say that there are no right answers in philosophy.

Yawn...this whole thing sounds rather arbitrary. Can a "representative" really represent hundreds, thousands, or tens of thousands of other people? -or better yet, can a representative even represent one other person on multiple issues over multiple years..?
You should read some Murray Rothbard. Instead of getting lost in conceptual mathematics for an evil institution, get down with practical logic. You were almost there with your jury nullification video
