I've heard it described as "Pollyannaism"

>As a result of the novel's success, the adjective "Pollyannaish" and the noun "Pollyannaism"[2] became popular terms for a personality type characterised by irrepressible optimism evident in the face of even the most adverse or discouraging of circumstances. It is sometimes used pejoratively, referring to someone whose optimism is excessive to the point of naïveté or refusing to accept the facts of an unfortunate situation.
