If we define optimism broadly as the tendency to maintain a positive outlook, then realistic optimism is the tendency to maintain a positive outlook within the constraints of the available "measurable phenomena situated in the physical and social world" (DeGrandpre, 2000, p. 733). With respect to fuzzy meaning, realistic optimism involves enhancing and focusing on the favorable aspects of our experiences. Examples include being lenient in our evaluation of past events, actively appreciating the positive aspects of our current situation, and routinely emphasizing possible opportunities for the future. With respect to fuzzy knowledge, realistic optimism involves hoping, aspiring, and searching for positive experiences while acknowledging what we do not know and accepting what we cannot know.
