Final answer:
People easily hypnotized likely score high in openness to experience, reflecting their curiosity and openness to new experiences, which correlates with hypnotizability.
Step-by-step explanation:
People who are able to be hypnotized easily are likely to score high on the dimension of openness to experience within the Big Five personality traits. This trait is characterized by attributes such as imagination, feelings, actions, and ideas. Individuals with elevated levels of openness are typically more curious, embrace new experiences, and possess a broad range of interests, which aligns with the susceptibility to hypnosis. In contrast, traits such as extraversion and agreeableness are not as closely related to hypnotizability, as they tend to describe social engagement and cooperative tendencies more so than openness to novel experiences and altered states of consciousness.
