Declaration bias refers to the tendency of individuals to make statements or declarations that align with their own beliefs, opinions, or interests, rather than presenting an objective or unbiased perspective. This bias can manifest in various forms, such as selectively sharing information, exaggerating facts, or ignoring contradictory evidence, in order to support one’s own viewpoint. It can also lead to the distortion of information and the promotion of personal agendas, ultimately hindering the pursuit of truth and objectivity. Declaration bias can be seen in various contexts, including politics, media, and personal relationships, and can have significant impacts on decision-making and communication.
