Before a PhD, which is better - knowing the exact kind of question you want to pursue, or having a broad interest in basic biology questions also fine?
Which of the above two kinds of students do you think are better prepared for a PhD? Those who know exactly what they want, or those who are flexible?
Second, what reason do they have to want "exactly" what they want....I mean, for some, it's family history of disease that motivates them...but for the rest, there is no reason to have a burning desire to answer a specific type of question- is that right? Thank you to all for responding.
I am asking specifically for Bioscience PhD in USA. It would be nice if you mention if you are a PhD student/postdoc/professor. Thanks!
