This predicament can be terrifying when you are in graduate school and you have to do your thesis.
Many folks are paralyzed and can t come up with an original idea.
They freeze and might even drop out with out appropriate mentoring and guidance. It might get worse, if you decide to become a professor - you will have to publish articles. Your chair will yell at you if you don't write. If you are not curious, don't bother to be a researcher. Scientific curiosity is the most important attribute you can have.
