Question

What is the one word for the following :
a) One who doesn't believe anything easily.
b) One who believes on anything without any proof.
​

Answer 1

Answer:

Fair. Believing without evidence is being gullible. If the source has been previously vetted, a fair mind would challenge any evidence that comes to it. For example, whenever Neil deGrasse Tyson starts talking about astronomy, I pay attention because I know his expertise far exceeds mine. I don't listen when politicians claim that climate change isn't true.
