What is the definition of 'gullibility'?

The term 'gullibility' refers to the tendency to accept something easily as true, without critical questioning or skepticism. This definition encompasses a lack of discernment, making individuals who are gullible more likely to believe false information, manipulation, or deceit. In practical terms, it suggests that gullible people may overlook evidence or reasoning that contradicts what they are being told.

The other choices do not align with this meaning. Being suspicious indicates a cautious approach and a tendency to doubt, which contrasts with gullibility. Conducting research implies a proactive and analytical mindset, which is also the opposite of accepting things without scrutiny. Lastly, being inquisitive involves curiosity and a desire to learn, not necessarily the blind acceptance of information. Therefore, the correct choice captures the essence of gullibility's definition accurately.
