in the study of geology, one often encounters the concept of pre-existing rock formations that challenge our understanding; it's like trying to go back to the beginning of earth's history. however, when conducting interviews with prominent geologists, a clever approach is to turn one's back on conventional questions and instead ask about the most reticent details of their work, thereby revealing secrets they're usually hesitant to discuss. this method can unexpectedly make experts disclose information they typically wouldn't, shedding light on controversial or overlooked aspects of their research, undermining their credibility or revealing personal biases in their work.
