When applied to research and academia, this bias can manifest in several ways, potentially impacting the integrity and outcomes of scholarly work.<\/p>\n<p><span data-contrast=\"auto\">Having this overtly positive underpinning then leads to researchers overestimating the chances of success which results in expectations that are overblown and unrealistic. Across disciplines and sectors, <\/span><span data-contrast=\"auto\">optimism bias<\/span><span data-contrast=\"auto\"> can result in weak or poor decision making and failure to assess risks clearly and realistically. <\/span><\/p>\n<p><span data-contrast=\"auto\">Take for example the case where managers may underestimate timelines and costs due to an overly optimistic outlook.
