What is the word to describe a person who does not have a personal opinion or stand on a subject?
If somebody says X is right, then you could agree. But if some other person says X is wrong, and you also agree, you are not really expressing your own opinion. You are simply agreeing with everyone else. How do you describe that kind of personality with one word in a formal way? Specifically, someone who cannot make decisions on their own and depends on others' opinions.
