Sortition: An Ancient Remedy to Heal the Organized Community’s Wounds

Posted on December 12, 2021 by Yoram Gat

Christopher Tripoulas writes in The National Herald, a publication aimed at the Greek American community:

For months now, the Federation of Hellenic Societies of Greater New York has been embroiled in an ugly dispute between rival sides. As the coordinating umbrella organization for local Greek societies, its primary function is to organize the annual Greek Independence Day Parade on Fifth Avenue.

Despite any criticism regarding its subdued presence in other issues of vital importance for the Greek-American Community or the manner in which it organizes the parade, the truth is that with the exception of Holy Week, it handles perhaps the largest and most recognizable collective Greek Community activity in America. This alone constitutes the resolution of the present dysfunctionality an immediate priority.

The organization of a parade, without clear objectives and messages, negates its very purpose. Although the parade takes place in a prime location and is covered live by a large metropolitan area broadcaster, there are still glaring issues. Whether it’s the lack of a stricter dress code for participants to promote uniformity and aesthetic beauty, or the failure to properly showcase student-marchers, considering that our Greek parochial schools are interspersed with no rhyme or reason, as if Hellenic Paideia was not one of the most critical issues for the survival of Hellenism, there are serious issues that need to be examined through public discourse, and not just in the anterooms of the Federation.

Ultimately, either the Greek-American Community will manage to prioritize certain common values around which it will work in unison and strategically to upgrade the institutions that express them, or it will come apart, because the ‘tropos’ or manner of its distinct otherness will no longer be discernible, leading to withering and dissolution.

This column proposes that the present administrative crisis can be overcome through the application of the ancient democratic practice of sortition; that is, distribution of offices via a lottery system. In his work ‘Rhetoric’, Aristotle notes that “a Democracy is a form of government under which the citizens distribute the offices of state among themselves by lot” (1365b-1366a). Hence, if the Federation leadership invokes democracy as a defining quality of its mode of governance, then there should not be any problem with accepting the distribution of offices according to its signature trait.

On the contrary, the revival of this ancient element of democracy would serve as a sterling example for other organizations, while showcasing an essential aspect of democracy that is frequently overlooked in contemporary society. And while this trait may escape popular attention, it is not altogether absent from modern democratic polities. Two characteristic examples from the United States regarding the contemporary use of sortition include the selection of jurors for trials, and the draft, which is currently not in use, but still a legal requirement laid out in the selective service system. Now, if many of us just happen to view the former as an imposition and waste of time, and ward off the latter, it’s worth questioning just how democratically minded we truly are…

Landemore in Foreign Policy

Posted on December 10, 2021 by Yoram Gat

Prof. Hélène Landemore has a hard-hitting new article in Foreign Policy magazine. From the outset, Landemore’s subtitle aims right at the heart of modern democracy dogma:

Democracy as it was envisioned was never about real people power. That’s what needs to change.

This radical attack on the electoralist system keeps on coming, paragraph after paragraph. Landemore seems ready now to finally correct the conventional terminology (the unwillingness to do away with this convention was a huge burden for her in Open Democracy):

The systems in place today once represented a clear improvement on prior regimes—monarchies, theocracies, and other tyrannies—but it may be a mistake to call them adherents of democracy at all. The word roughly translates from its original Greek as “people’s power.” But the people writ large don’t hold power in these systems. Elites do.

Representative government, the ancestor of modern democracies, was born in the 18th century as a classical liberal-republican construct rather than a democratic one, primarily focused on the protection of certain individual rights rather than the empowerment of the broader citizenry. The goal was to give the people some say in choosing their rulers without allowing for actual popular rule.

The Founding Fathers of the United States, for example, famously wanted to create a republic rather than a democracy, which they associated with mob rule. James Madison, in particular, feared the tyranny of the majority as much as he disliked and rejected the old monarchical orders.

Another important attribute of the article is that Landemore is making it explicit that exclusion from government is not merely a matter of making people “feel involved”, but rather translates into unrepresented interests:

Large Scale Secure Sortition Part 3: What exactly did Cleve show was impossible? And what possibilities are left?

Posted on December 5, 2021 by graytmatter

This article assumes you’ve read my previous article “Large Scale Secure Sortition Part 1: Generating Randomness Collectively with In-Person Gatherings”. In particular it assumes a familiarity with the add-divide-remainder procedure for combining individual submissions to get a final random result.

This article explains the mathematical structure that makes collectively generating randomness difficult and introduces the four major approaches that can lead to systems that work. To do this we’ll go through a version of Cleve’s 1986 impossibility proof and call out the four major assumptions he makes as he makes them. Then we’ll explain how reversing each of those assumptions leads to a working method of collectively generating randomness and talk about its pros and cons.

In the world of CS theory the process of collectively generating randomness is called “multiparty coin flipping” and the seminal paper that kicked off the field was Cleve’s 1986 impossibility result. The paper proves that “it is impossible to have perfectly fair multiparty coin flipping unless a majority of those helping to ‘flip the coin’ are behaving honestly.” But if you keep digging you start finding papers that claim to have methods for fair multiparty coin flipping when just a single person is behaving honestly. Cleve’s proof was correct, but it made some specific assumptions about how those trying to flip the coin were able to structure their communications and what they wanted out of the process. Multiparty coin flipping is only possible if you take at least one of those assumptions and assume the opposite.

The first assumption is that at least half of the participants are dishonest (when we reverse this assumption later we assume that less than half of the participants are dishonest). Cleve is very upfront about this assumption and it is a good one to keep when thinking about designing sortition systems.

I’ll call out the other assumptions as the proof makes them. Let’s dive in.

The Proof

Imagine that Luka and Hugo instead of flipping a collective coin in person have to do it over text. The basic rules are the same: they both flip a coin, Hugo wins if they are both the same(heads heads or tails tails), Luka wins if they are different(heads tails or tails heads). If they both just send the results of their coin flip there’s a big problem. If Hugo sends his result (heads) first, Luka has the opportunity to lie about his (it actually came up heads, but he can say tails) and win unfairly. Or vice versa. Maybe they can agree to both send their result at exactly 12:00, but because online messages can take several seconds to arrive Luka might not be able to tell the difference between a message actually sent at 12:00 and one held back a moment and changed. If we are defining a formal way of collectively generating randomness online we have to assume that they trade off talking (Luka talks, then Hugo talks, then Luka talks). There’s no way to ensure any desired overlap. (This is the proof’s second assumption, and it’s a good one for online communication).

Large Scale Secure Sortition Part 2: “Voting” from home with Non-Malleable Time Lock Puzzles

Posted on December 5, 2021 by graytmatter

This article assumes you’ve read my previous article “Large Scale Secure Sortition Part 1: Generating Randomness Collectively with In-Person Gatherings”. In particular it assumes a familiarity with the add-divide-remainder procedure for combining individual submissions to get a final random result.

This article proposes a backup protocol to compliment the one in the previous article that can be used without requiring people to gather in person. However it is so mathematically complicated that only CS and Math PhDs are likely to ever understand the proof of why it’s secure. Given that the goal of using these systems is to generate trust, I cannot recommend this as a primary option, though I can recommend it as a fallback during times (like extreme weather events or pandemics) where gathering large numbers of people is difficult.

Non-Malleable1 Time Lock Puzzles are cryptographic tools that allow you to hide information inside a computational puzzle. Once hidden, the information can only be accessed after the puzzle is solved. Making a time lock puzzle is kind of like turning a QR code into a jigsaw puzzle. If you give the puzzle to someone they’ll only be able to scan it after they’ve completed/solved the puzzle. The main difference is that Jigsaw puzzles can be solved in many different ways by doing the “this piece connects to this piece” steps in any order. Time Lock Puzzles can only be solved in 2 ways.

The first (called opening) is fast but requires a special key that is created alongside the puzzle and known only by its creator. The second (called forced opening) takes much longer and requires you to do a specific list of computations in a specific order. These computations have to be done sequentially (you only know what step 2 is after you finish step 1) so throwing hundreds of computers2 at the problem isn’t any better than using just one. When you create the puzzle you get to decide exactly how many steps it’ll take to solve the puzzle (by choosing how many “puzzle pieces” there are). And since we know about how quickly modern computers can do these steps, we can accurately estimate how long the puzzle will take to solve.

Large Scale Secure Sortition Part 1: Generating Randomness Collectively with In-Person Gatherings

Posted on December 5, 2021 by graytmatter

Matthew Gray is a Mathematician, Software Engineer, and Theoretical Computer Scientist currently teaching at Renton Technical College after working at Microsoft Norway. His primary research interests are in Secure Multiparty Computation, Quantum Cryptography, and Coding Theory. Over the last year he has been researching how sortition can be conducted in secure and trustworthy ways.

Judging from the aftermath of contested elections around the world, if large numbers of people question the fairness of a sortition selection there could be dire consequences. Our current systems for generating the randomness needed for selections are not secure enough to silence those questions, especially when used to select national representatives. The current systems are all centralized and non-participatory, some are vulnerable to local cheating, and all are vulnerable to sabotage from well-resourced malicious actors, such as state security services. This article proposes a new option. It lays out a specific decentralized and participatory method of selecting representatives by explains how two people can go about fairly choosing one of them to be selected and then showing how the method can be scaled up for larger selections. It also touches on some of the mathematics surrounding these methods.

Current systems for generating the randomness needed for drawings fall into two main categories. First are physical systems such as dice, floating balls, or names in hats. These work better in small communities where every member can show up and observe. But even in those spaces, if people distrust their neighbors, they will worry about the dice being weighted or someone sneaking extra copies of their name into the hat. Second are digital systems that take some outside sources of randomness and process them to get some final randomness. These outside sources of randomness include stock market indexes, lava lamps, or cameras whose lenses have been painted over. 

Digital systems tend to involve math that is fairly complicated, don’t feel that random, and aren’t interesting to look at. Also, because of the complicated math involved, there’s a chance that these processes aren’t actually random after all. Neither category produces systems that involve citizens or are particularly resilient to sabotage efforts. Weighting dice or hacking a computer is easy. Manipulating the stock market is hard but may not be beyond the abilities of a state security service. However if we include everyone in the process of generating the randomness we can create systems that have no single point of failure.

To introduce the ideas used by the system I am about to propose, let’s imagine that the team captains (Luka and Hugo) in the last FIFA World Cup didn’t trust the coin that was going to be used at the start of the match. One way they could generate the “coin flip” together is for both captains to bring their own coins and flip them simultaneously. If both coins land on the same side (i.e. both heads or both tails) then France wins the coin toss, if they land on different sides (i.e. heads tails or tails heads) then Croatia wins. What is important to note here is that even if one coin is weighted, as long as the other one is unweighted, then the overall “coin flip” is fair. 

Figure 1. The odds of each possible result when one captain brings an 80/20 coin, and the other brings a 50/50 coin.

Gauchebdo: Sortition – a false solution

Posted on December 4, 2021 by Yoram Gat

The following piece was recently published on Gauchebdo (“Left Weekly”), a Swiss website which bills itself as “a platform for men and women who resist, the voice of those who propose to change society”.

Sortition – a false solution
Anaïs Timofte

Sortition has become over the last few years an idea which is garnering increasing attention. Whether in the context of deliberative citizen assemblies concerning the climate, or of the selection of candidates for the executive bodies of social movements, or of the random ordering of candidates on an electoral list, there is no shortage of examples.

Some promoters of sortition go farther and see it as an alternative mode of representation and to the election of parliament members. They see is as a way to “renew the democratic process” having the advantage of dissipating the “elitism” of the electoral process. But is this really the case?

Greek origins

Sortition is far from being a new idea. The most famous example is that of Athens in ancient Greece. The Council, composed of 500 Athenian citizens wielding significant legislative and executive powers, was allotted in a well defined and controlled process. In order to handle numerous tasks, the allotted citizens had at their disposal “public slaves”, owned by the city, whom they managed.

Other examples often evokes as part of the history of sortition are those of the medieval communes of 13th century Italy: Verona, Venice and Perugia. These cities developed modes of selection combining elections and sortition.

Sortition and capitalism

Even though there is something intriguing in the idea of imagining the powers-that-be reproduce today sophisticated (and largely fantastic) selection methods used by the Athenian democracy and of Venice of the Doges, it is nevertheless necessary to understand sortition within the framework of the current capitalist system and within the framework of the organization of working classes that aim to move beyond this system. 5 point of criticism may be raised:

First, sortition leads to a depolitization of the process of selection, and more precisely, a dissipation of class conflict. The candidates no longer need to defend ideas or a conception of society – their individual or social-professional characteristics suffice.

Sortition for judges on the ballot in Switzerland

Posted on November 23, 2021 by Yoram Gat

The Swiss Radio Lac reports:

Sortition is proposed

[In addition to other proposals] the Swiss will also have to vote [on November 28th] on the proposition regarding the judicial system. The proposition would institute appointment of judges using sortition in order to make them more independent. Official languages would have to be equitably represented and the judges would be able to serve up to 5 years beyond the normal age of retirement.

Parliament has rejected the text, without offering a counter-proposition, either direct or indirect. According to the elected, sortition would not guarantee better independence or better equality. Moreover, it would damage the democratic legitimacy of the judges.

Judges in Switzerland are currently appointed by the Swiss Parliament and they need to be re-appointed periodically. The notion that this provides judges with “democratic legitimacy” runs against standard liberal dogma:

At present, the Swiss parliament awards the posts of federal judge according to party strength. Judges with no political affiliation thus have no chance of gaining office.

When a judge is elected, she or he has to hand over money to the party – the so-called mandate tax, which is unique in the world, and constitutes an important source of funding for parties. In return, the judge can count on party support when it comes to re-election.

In this system, the judiciary is therefore politicised. Judges can be influenced by their party membership when passing verdicts, as studies have shown. And not just out of ideological considerations. Parties sometimes also exert tangible pressure. If they do not approve of a ruling, they can threaten not to re-elect the judge.

This mutual dependence calls into question the independence of the judiciary and the separation of powers. […] The Council of Europe’s Group of States against Corruption (GRECO) has also rebuked Switzerland.

Citizens’ Assembly in Bosnia and Herzegovina

Posted on November 21, 2021 by paulnollen

The EU delegation to Bosnia and Herzegovina reports:

The EU in BiH [Bosnia and Herzegovina] has launched the Citizens’ Assembly, an innovative model of deliberative democracy, which offers a unique opportunity for citizens in BiH to directly express their views on constitutional and electoral reform, to recommend concrete solutions for elimination of the discriminatory provisions in the BiH Constitution as well as for improvement of the Election Law. This process is based on two rounds of sortition, practice of random selection of citizens as a representative sample of a country’s population. During the preparatory phase of the process a team of local and international experts and the independent company specialized in polling representative samples of the BiH population (IPSOS) jointly developed the methodology for random selection of citizens’ and completed the first round of sortition. The letter signed by the EU, the US and OSCE Ambassadors in BiH was sent to 4,000 randomly selected households in BiH, inviting citizens to express their interest in participating in the Citizens’ Assembly.

Short refutations of common arguments for sortition (part 2)

Posted on November 17, 2021 by Yoram Gat

Part 1 is here.

The two arguments presented below pin the problem with elections on the voters.

4. The masses are rationally ignorant. Therefore any system that relies on their judgement would not function well. Sortition does not rely on mass judgement.

According to this argument elections present a variety of choices to the voters, with some of these choices being on the whole materially better than others as measured by the interests and values of the voters. The voters, however, each knowing that the impact of their vote is tiny, are too selfish (or more politely, too busy taking care of their private business) to spend the time and effort to determine which candidate or party are better than others. Instead they hope that others would do the work for them, and in this way they would save the effort of figuring out which alternatives are the better ones but at the same time they will enjoy the good outcomes of other people’s choices. But since everybody, or at least the large majority of voters, follow the same calculation, almost everybody is uninformed and as a result when they arrive at the voting booth, they often select poor alternatives.

All this sounds very sophisticated and has the stamp of approval of the economists and rational-choice theorists. The argument suffers, however, from at least two severe problems. First, the assumption that the electoral alternatives present to voters a meaningful choice is theoretically problematic. Since the electoral choice is between elite factions, the range of choice must be severely limited. The factions of the elite all share certain elite values and interests that any of them will promote if and when they are in power. The promotion of those values and interests is often made at the expense of the values and interests of the general population, making the policies pursued by government – regardless of the elite faction in power – detrimental to the general population.
