Low-latency mediums are usually event-based ("Breaking News! You can't guess what just happened!").
High-latency mediums have the time to be understanding-based.
"we must get the story online within 5 minutes of it happening"
and
"Story written over a few hours/days/weeks and then published online"
However, I don't think it prevents bias, either from the authors own ideology or the status-quo at the time of writing.
EDIT: Also, access to past facts can be limited as well. History being written by the victors, etc.
Sometimes it's good to listen to their old podcasts and read their old articles and ask yourself if anything in those old podcasts and articles is still relevant. Did they recognize events changing the world or where they just focusing on clickbait B.S. The mark of crappy news is that if you read news from it a year ago absolutely none of it will matter now.
Generally speaking Hacker News focuses on upper middle class American issues. When we talk about the less well off its generally from the top looking down. Watch next time for the comments of the form "I'd gladly pay more taxes so XYZ wouldn't have to go through this". Few commenters ever truly see themselves personally getting into one of these situations.
In terms of politics this site is heavily westernized. Communism and the Chinese system does have some nice features (along with the bad), but its rare to see threads here explore the benefits.
None of this is necessarily bad, and I'd argue this site gives you a broader view of the world than reading traditional news. However its far from a zeitgeist of what's "really happening" in the world.
The quality of the downvotes depends on the quality of the community.
Read science. Actual science not studies paid for by X industry/gov. That will learn you everything else.
Yes, this is hard. Probably more than one person can do. Which is why it is safe to assume you, nor anyone else who is talking at you knows what they are talking about.
What science isn't funded by either industry or government?
My meaning was, that you should learn science. Not just listen to what people tell you that sounds "sciency".
