Some people argue against both optimism and pessimism in favor of so-called realistic thinking. They distrust optimism on the grounds that it causes us to sugercoat problems, discount risks, and exaggerate the upside. Pessimism, on the other hand, is criticized as too downbeat, de-energizing, and generally damaging in its impact. This crown prefers realism as the neutral and objective middle ground.
