What term describes someone who is inclined to believe things readily without substantial evidence?

The term that best describes someone who is inclined to believe things readily without substantial evidence is "gullible." A gullible person is easily deceived or tricked because they tend to accept information without questioning its validity or seeking proof. This characteristic often leads to a willingness to believe in things that may not have a solid foundation, making them susceptible to misinformation and scams. Understanding this term is vital, as it highlights the importance of critical thinking and evaluation of information before accepting it as truth. Other options, while related to belief and evidence, represent different attitudes or dispositions; they do not convey the same level of readiness to accept without proof as "gullible" does.
