Studies

Hello Rabbi,
I have a question that has been bothering me for a while, and it is how can one formulate a position in the age of research, and how can one exchange opinions like that?
I happened to notice many conversations between people I study with, and each one, in order to strengthen their position, used "there are studies that show…". How am I, as an individual, supposed to formulate a position on who is right? And what is right? After all, every apparent position has studies and their opposites, and I also don't think it makes sense to read each study individually.
I would be happy for an answer.
