Negative describes something unfavorable or harmful, a pessimistic attitude, a “no” answer, and, in math and science, a value less than zero or an opposite electrical charge. “A negative review,” “she’s always so negative,” “the test came back negative,” and “a negative number” all use the word for related but distinct ideas: unfavorable quality, pessimism, absence of something, and mathematical value.
Unfavorable and adverse both keep the “harmful or bad” sense of negative, while pessimistic and cynical fit the attitude sense specifically, and unfavorable or below-zero fit the mathematical sense. Picking the sharper synonym starts with identifying which of these senses “negative” is carrying.

Start by identifying whether you mean an unfavorable outcome, a pessimistic attitude, or harmful impact specifically.
For describing attitude specifically, “pessimistic” or “cynical” are more precise than the broader “negative.” Example: “His cynical outlook made every project feel doomed from the start.”
