Panglossian describes optimism carried to a very high degree, sometimes so high that it can ignore warning signs. The word comes from Voltaire's character Dr. Pangloss, who insisted that everything was for the best even when events were clearly painful. Because of that history, the term can be warm or critical depending on context.

Used carefully, panglossian can still point to a resilient mindset that refuses to collapse under pressure. The key difference is whether optimism remains grounded. Productive optimism helps people act, adapt, and recover; blind optimism can prevent needed course correction. The word captures that tension in a single adjective.
