“Williams and others have also noticed that high openness appears strongly related to the ability to recover from stressful events. So what does it mean to be “open”? The trait is broadly characterized as comfort with novelty and desire for “cognitive exploration.” To measure it, psychologists use the extensive five-trait questionnaire called the NEO (the abbreviation stands for the first three categories: neuroticism, extraversion, openness). The openness category breaks down into five clusters of questions designed to gauge imagination and fantasy, adventurousness, attentiveness to inner feelings, tolerance of others’ viewpoints and ideas, and ability to appreciate and be moved by aesthetic experiences. People scoring high on openness really feel things, and they’re tuned in to how they’re feeling them.”
