Protecting and Restoring New Zealand's Biodiversity

Scoop and PEP invite you to help decide how we should protect and restore our biodiversity over the next 50 years using Scoop’s online engagement platform, HiveMind.

This Biodiversity HiveMind is one way for you to take part in the DOC-led public consultation on proposals for a new Biodiversity Strategy for Aotearoa New Zealand. (NZBS)

You can vote on other people’s statements and add your own statements in the Biodiversity HiveMind Engagement window below until 11 September 2019. Voting will continue until the HiveMind closes on 22 September 2019. Please vote on all statements before submitting your own statement to avoid double ups. You must comply with Scoop’s Terms and Conditions.

Summary of the Comment Section

This section highlights various methods for selecting a small set of comments that best capture the broader conversation (see the comment section below).

Each method focuses on a different perspective, emphasizing principles such as popularity, representation, or diversity. This leads to different voices being represented. Explore the section below to get a sense of the impact these approaches have.

Explanations

Analysis

Popularity measures how popular is a set of comments for the participants. It is equal to the total amount of positive votes (a.k.a. thumbs-up, or approvals) received by the comments in the selection.

Inclusion measures the percentage of participants included in the selection. That is, the percentage of participants who expressed a positive opinion (a.k.a. thumb-up, or approval) about at least one of the selected comments.

For instance, an inclusion of 60% means that 60% of the participants feel positively about at least one comment of the selection.

Selection Methods

A selection method is a procedure that selects a given number of comments based on the votes submitted by the users.

The desired number of comments to select is always given up-front.

Approval Voting: Selects the comments who have the highest number of votes.

Satisfaction Approval Voting: Selects a set of comments that maximises the total average satisfaction of the participants. The average satisfaction of a participant is defined here as their satisfaction divided by number of supported comments.

Sequential Proportional Approval Voting: Sequential variant the proportional approval voting method. Selects the comments one by one, each time selecting the best non-selected comment according to the principles of proportional approval voting.

Method of Equal Shares: Each participant receives an equal amount of virtual currency to spend on comments they feel positively about. Comments are considered in rounds. A comment is selected if its supporters have enough budget left to collectively afford it.

Method of Equal Shares with Approval Voting Completion: Applies the method of equal shares. If fewer than the desired number of comments are selected, the result is completed by using the approval voting selection method.

Method of Equal Shares with Increment Completion: Calculates the minimum amount of virtual currency needed for the method of equal shares to select the desired number of comments. Then, applies the method using that amount.

Eneström–Phragmén: Distributes representation load evenly among participants to select a proportionally representative set of comments.

Phragmén's Sequential Rule: Sequentially adds comments while balancing the representation load to maintain proportional fairness.

Chamberlin–Courant: A participant is considered to be represented if their satisfaction is more than 0. This method selects comments to maximise the number of represented participants.

Proportional Trichotomous Voting by Kraiczy, Papasotiropoulos, Pierczyński & Skowron, 2025: A trichotomous extension of the PAV rule in which both approved and selected alternatives, as well as disapproved and not selected alternatives, contribute positively to the score.

Proportional Trichotomous Voting by Talmon and Page, 2021: Maximizes the difference between (1) the PAV score based on approved and selected alternatives, and (2) the PAV score based on disapproved but selected alternatives.

Proportional Trichotomous Voting by Hervouin, 2025: Maximizes the sum of (1) the PAV score for approved and selected alternatives, and (2) the PAV score for maximum number of comments to select minus the number of disapproved but selected alternatives.

Sequential Phragmèn for trichotomous profiles: Sequential Phragmén adapted for trichotomous ballots.

Taxed Sequential Phragmèn for trichotomous profiles: Runs Phragmén’s sequential rule on a participatory budgeting instance where each project's cost equals a tax for selecting it. The cost of a project is equal to its approval score divided by its support (the number of approvals minus the number of disapprovals).

Taxed Method of Equal Shares by Kraiczy, Papasotiropoulos, Pierczyński & Skowron, 2025: Applies the Method of Equal Shares (MES) to a participatory budgeting instance where each project's cost equals a tax for selecting it. The cost of a project is equal to its approval score divided by its support (the number of approvals minus the number of disapprovals).

Maximum Satisfaction for trichotomous profiles: Selects the comments so to maximise the total satisfaction of voters. Each voter's satisfaction equals the number of approved and selected alternatives minus the number of disapproved but selected alternatives.

Chamberlin-Courant for trichotomous profiles: Selects the comments so to maximise the number of voters with positive satisfaction.
