When you view a discussion, by default, the voting bars show the average of all votes on each claim. However, you can change the perspective you view the discussion from at any time, to show the votes of a particular user, of a group of users, or a custom perspective.
To change perspective, go to the discussion menu (click on the three horizontal bars at the top-left of the screen), and select ‘Perspectives’. Select the perspective you would like to view the discussion from, or click ‘Create New’ to create a custom perspective.
A custom perspective allows you to artificially vote on claims in a discussion to demonstrate a particular point of view - for example, the view you think a particular expert would take. After clicking ‘Create New’, enter a title for your perspective and click ‘Save’. To vote as the custom perspective, ensure your perspective is set to the intended custom perspective, and vote on claims accordingly.
