What does it mean if someone is said to exhibit "gravitas"?

When someone is said to exhibit "gravitas," it refers to their ability to present themselves with a serious and dignified demeanor. Gravitas is often associated with a sense of weightiness or seriousness, which conveys a deep respect for the situation, issue, or audience at hand. People with gravitas tend to command attention and convey authority, often in professional or formal settings, making their words and actions carry more significance. This trait is particularly valued in leaders, public figures, and individuals in positions of influence as it suggests reliability and decisiveness.

The other options describe qualities that contrast with gravitas. For instance, displaying humor and lightheartedness generally suggests a more casual or relaxed demeanor, which may not convey the seriousness implied by gravitas. Carelessness and lack of formality indicate a disregard for the seriousness of a situation, while insecurity and hesitation suggest a lack of confidence that undermines the dignified presence associated with gravitas.
