Final answer:
Assessing a potential friend's dependability pertains to the personality trait of conscientiousness, one of the Big Five personality traits. Conscientious individuals are often reliable, organized, and responsible, which are qualities that align with someone being a dependable friend.
Step-by-step explanation:
When evaluating a potential new friend for their dependability, you're essentially probing into a key aspect of personality traits. The question of dependability is directly related to the personality trait known as conscientiousness. People who exhibit high levels of conscientiousness are typically reliable, well-organized, self-disciplined, and responsible - qualities that align with someone being dependable and trustworthy.
