Taking a stance frames results for the writer, such that they are less likely to write about points of the opposing side or express skepticism towards findings on theirs. I'd rather understand the situation regardless of how much it advantages my preference than gain a false understanding. Most issues are nuanced yet interest in covering things in this manner seems to be more rare over time. You have to hope you can cobble this together by looking at both sides, establish what's true, perhaps if lucky run into an insider / impartial sources (which is why I come back to HN).
