The characteristic that defines someone as "gullible" is their tendency to believe and trust others easily. This disposition means that gullible individuals often accept statements or claims at face value without exercising critical thinking or skepticism. This can make them vulnerable to deception or manipulation because they may not question the intentions or truthfulness of others.

In contrast, the other choices do not align with the definition of gullibility. For instance, an inability to feel emotions would not indicate a person's inclination towards believing others; it suggests a different psychological profile. Intellectual curiosity refers to a desire to learn and explore ideas critically, which generally involves questioning information rather than accepting it blindly. Being a skilled negotiator implies a level of shrewdness and strategic thinking that typically counters gullibility, as such individuals are adept at evaluating the motives and tactics of others.
