Pollster Identity 1. Name: This category records the self-identified name used by the organisation claiming to conduct political polling through representative surveys. 2. Registration: This category records whether a given entity is legally registered with the state and, if so, for how long. If an organisation has been registered for a longer time, it is more likely to have accumulated experience and is more likely to be seen as credible among partner organisations and clients. 3. Key People: This section highlights the individuals responsible for the research, or other professionals involved in the organisation conducting it. This section can help make transparent whether key individuals have conflicting interests (e.g., partisan affiliations) which can hamper science-based work. 4.

It allows consumers to access key information related to an entity, including, but not limited to, the aspects we focus on in our study.
