Kialo


Kialo is an online structured debate platform with argument maps in the form of debate trees. It is a collaborative reasoning tool for thoughtful discussion, understanding different points of view, and collaborative decision-making, showing arguments for and against claims underneath user-submitted theses or questions.
The deliberative discourse platform is designed to present hundreds of supporting or opposing arguments in a dynamic argument tree and is streamlined for rational civil debate on topics such as philosophical questions, policy deliberations, entertainment, ethics, science questions, and unsolved problems or subjects of disagreement in general.
Argument-boxes are structured into hierarchical branches where the root is the main thesis of the debate, enabling deliberation and navigable debates between opposing perspectives. A debate is divided into Pro and Con columns where registered users can add arguments and rate the of the parent claim. The arguments.
Its argument tree structure enables detailed scrutiny of claims at all levels of the tree and allows users to for example quickly understand why a decision was made or which of the aggregated arguments swayed it this way. Newcomers can join a debate at any time and look back at the structured discussion history, and then weigh in at the right place with their new argument or their comment on a specific argument. The design presets a structure on debates "that allows participants to easily see, process, and ultimately assess the many facets of competing claims".
The word Kialo is Esperanto for "reason". The platform is the world's largest argument mapping and structured debate site.

Overview

Users can comment on every Pro or Con, for example for requesting sources or expansions. Recent activities of a debate are shown in a panel on the right side of the respective debate. Debates can be found through the search or on the Explore page through their descriptions and topic-tags.
Mere comments that do not make a constructive point are not allowed and are picked up by other users and moderators. "Civil language and sensible observations from opposing perspectives" can be seen also in debates about controversial topics. The site by-design incentivizes fair, rigorous, open-minded dialogue. Contributors making claims often also write counterpoints to their own contribution. Claims need to be shorter than 500 characters and can link to external sources.
Debate trees can also start off with multiple theses – such as or hypotheses. Claims can link to related debates or include segments of them. In the discussion tab of each claim, users can make edit proposals, decide if the argument should be moved or copied to another branch, call for archiving a claim, and ask for extra evidence or clarification.
Debates can grow large and complex for which a sunburst diagram and the search functionality can be useful. Each debate also has a chat-box. In cases where e.g. a "Con" is a point against multiple in the "Pros", users – through moderators – can link these arguments at the respective places to avoid duplication of content and allowing a clean chain for people to understand which points are arguments against each other. Contributions of users are tracked, enabling a board of thought-leaders for every debate. Other gamification elements include a feature to thank users for their contributions.
The "Perspectives" feature allows users to see 'Impact' ratings of supporters and opposers of a thesis as well as of the debate's moderators and individual contributors. It thereby enables participants to see a debate from other participants' perspectives and to sort by them. In Kialo Edu, this feature lets teachers view votes for a whole class, individuals, or supporters/opponents of a specific thesis. Users in both versions of Kialo can vote on the overall debate topic as well as on individual claims to express their perspectives or conclusions, with the rationale why they voted on the veracity of the thesis as they did not being captured. Voting can be done by any registered user while navigating through any debate that has voting enabled or via using the Guided Voting wizard user interface that automatically walks through branches.
As of 2021, Kialo doesn't have a mobile app.

Contents

A 2018 report stated the collaborative argument platform hosts more than 10,000 debates in various languages. It also hosts private debates. The website claims that it has over 18,000 public debates as of July 2023, as well as over 1 million votes and over 720,000 claims. Debates can be found via the site's internal search and up to six tags per debate.
Preprint studies have scraped public debates on over 1.4K issues with over 130K statements as of October 2019 and 1628 debates, related to over 1120 categories, with 124,312 unique claims as of June 26, 2020.

Kialo Inc.

The site is run by Kialo Inc. It was founded by German-born entrepreneur and London School of Economics and Political Science graduate Errikos Pitsos in August 2017 and is based in Brooklyn and Berlin. According to a 2018 report, the site does not show advertisements and does not sell user's data. The for-profit company was founded in 2011, Pitsos began to develop the concept in 2012 and described various specifics of the system in 2014. In 2018, he stated that they intend to make money by selling the platform to companies as a deliberation and decision-making tool. The site is free to use for the public and in education. According to the site, as of 2023 Kialo.com is a non-revenue generating site with no ads and no reselling of user data.

Applications and adoption

Adopted applications

Applications of its content or the platform in society include:
  • Teachers and professors, especially in high schools – including the universities Harvard and Princeton, are using Kialo for class discussions and exercises in critical thinking and reasoning, as consolidating understanding of materials covered in recent classes, more useful and engaging learning experiences, for remote/e-learning, for clearing up misconceptions, teaching logical fallacies and rational argumentation, for academic dialogue, teaching media literacy, and for teaching to sufficiently reflect or research before posting online. Like for debaters of the main site, access for schools and universities is free. is the custom version of Kialo specifically designed for classroom use where debates are private and locked to invited students.
  • *Kialo allows teachers to provide feedback to students on their ideas, argument structure, and research quality while it is left to other students to rate the impacts of their peers' arguments.
  • *Students can be allowed to contribute anonymously which may be useful for controversial issues as well as for safeguarding privacy in education.
  • *Students are or can be encouraged to back up their claims with evidence which can foster digital literacy and research skills.
  • *Students and teachers can use it to arrange their thoughts when structuring an essay or project.
  • The site's name was decided on internally using the software.

    Prototypical and theoretical applications

Potential, theoretical, prototypical or little-used applications include:
;Education
  • Improving critical thinking skills of society at large as well as facilitating deep or efficient thinking and deepening research and debates where e.g. discussions are less shallow and the well-known or many arguments have already been made and in many cases aren't unreasonably over- or underrated.
  • * Pitsos claimed that "we're training students to be very good test-takers instead of critical thinkers", suggesting teaching people to think things through may be more important or neglected compared to essay writing skills.
  • Many young people and adults are "submerged into a sea of dispersed information", "rowsing and engaging in superficial thinking activities". Kialo could counteract this issue and help people develop good sane reasoning.
;Academia, R&D and policy
  • Three scholars from three prestigious U.S. universities outlined possible benefits in this domain, including applications beyond higher education such as for academic communication. They suggest the debate platform could be used for structuring the communication of open peer-review by helping those giving feedback to "hone in on core arguments and pieces of evidence in an even more direct way" than annotated commenting.
  • It could be used to evaluate extracted argument structures and sequences from raw texts, as in a Semantic Web for arguments. Such "argument mining", to which Kialo is the largest structured source so far, could e.g. be used to assess the completeness and effectiveness of an argumentative discussion or to augment it.
  • A security studies paper suggested it could be used for "managing arguments more effectively than traditional paragraph/bullet-point approaches". It claims that "complexity demands adaptation" but also notes that "Kialo's simplicity does pose some weaknesses and limitations, and in general current systems cannot reliably automate analysis or synthesis of arguments in the same way that statistical packages can automate analysis of data".
  • The site could be used by companies and government organizations as "intuitive debate software for internal discussions and decision-making".
  • It could aid in the search for the best policies and course of action, including for 'wicked problems' and issues where there is a large polarization. This may include "experiments of deliberative democracy inside local governments".
  • With a platform like Kialo, users provide "both data on what they see is in the landscape of relevant arguments but also some indication of what they think is important in determining their policy preferences" and "also shows which arguments the individual did not find persuasive, and possibly which rebuttals to a particular argument used to discard it." Current functionality of the site may still be insufficient for the latter outside of experiments.
  • It could increase efficiency in knowledge acquisition, including concerning information overload on social media.
  • Policy-makers and scientists could use platforms and debates like these to engage with each other as well as the public if they were aware of it and used it. Considering only argument trees beneath theses, its arguments-crowdsourcing and revision principles are not or less vulnerable to framing-issues, intentionally placed attackable segments, weak or missing arguments, straw man points, oversimplification, agenda-setting and other issues that may be common in contemporary public political debates.
  • The debate trees can be used to identify arguments that are seen as most credible, as well as reveal which areas of argumentation lack support, precedent, or evidence, which may be useful for subsequent work or more efficient and useful science.
;General
  • Writers in general, as well as possibly major other opinion leaders, could populate a Kialo debate with their arguments and release it alongside the traditional linear written format, albeit such would mean the arguments would be open to scrutiny, with such being more accessible than large and fans-dominated unstructured comment sections or may already be part of an existing debate tree. They could also use the site in other ways such as for selecting questions to pose to interviewees or for selecting unexplored questions to investigate and report on.
  • It could be used for legal cases.
  • Websites could embed read-only argument trees from the site.
  • More broadly, the site's content could be used for reflective brainstorming, and as a crowdsourcing resource for points to use in other media. It enables detailed exploration of some theses or topics as the visual reasoning through tree-based structure allows for many levels of depth and for follow-up questions in the discussion tab of each claim. The founder stated that "The public debates are basically supposed to become a site where people can go and inform themselves. If a debate has over 2,000 unique arguments, it's going to be hard to find an argument that's not in there already. You can go there, similar to Wikipedia, and read."
