What does the word 'callous' imply about a person's emotional state?

The word 'callous' describes a person who shows a lack of empathy or concern for others' feelings, suggesting an emotional state characterized by insensitivity. This term is often used to refer to individuals who are unfeeling or emotionally hardened, which aligns perfectly with the idea of being insensitive to the suffering or needs of others. People who are callous may dismiss or overlook the impact of their actions on those around them, indicating a significant deficiency in emotional awareness or compassion.

In contrast, the other choices like empathetic, compassionate, and thoughtful all reflect positive qualities associated with emotional awareness and sensitivity towards others. These words suggest a caring and considerate disposition, which stands in direct opposition to the notion of being callous. Hence, the correct answer encapsulates the essence of emotional insensitivity inherent in the term 'callous.'
