Opinion library


Exploring mask controversy words

What do change.org users think about mask mandates? Opinion Library allows to understand the language used to express different positions on the mask mandate issue in the United States.

The research examined petitions published on change.org during the pandemic, as reported in Sign here to fight pandemic. The aim of this website is to make the dataset used in this research available to researchers and potential activists interested in the subject. To do this, we set ourselves the objective of realising a tool to explore the language and arguments used in comments to petitions regarding the mask mandate in the United States.
