the.com/positivity

means The practice of focusing on hopeful, constructive aspects of a situation rather than dwelling on the negative.

from Traces back to Latin 'positivus' (settled, fixed by agreement, rather than natural law), via French 'positif.' Philosophers in the 1800s used 'positivism' for a worldview grounded only in observable fact. The warm, self-help glow of 'positivity' — cheerful outlook rather than philosophical stance — is a much later, softer drift of the same root, picking up steam through 20th-century psychology and the self-improvement industry.
