Once you’ve selected a major, one way to develop a sense of the types of questions posed in your selected discipline is to read articles published in that field. For example, read a few articles published in the field and identify the questions these articles raise at the beginning of the texts. Of course, these questions are not always explicitly stated, so identifying an article’s motivating questions might take some work
Reading and researching more about your interest can provide you with different point of views and give you a second hand opinion on things. This can therefore change your own understandings of a certain topic and provide you with a new set of questions.
