In this world, the vast majority of people cannot distinguish between news and propaganda.

Many think they are obtaining information, but they are actually receiving curated conclusions.
The key difference between the two is not in truthfulness, but in approach:
News is more like laying out facts and processes, allowing uncertainty, so you can judge for yourself;
Propaganda directly provides conclusions, using simplified narratives, filtering information, and emotional guidance to complete your thinking for you.
When a complex issue is presented too smoothly, clearly, or even makes you immediately "understand," you should be cautious—
It may not be that the world is truly like that, but that you have only been given one explanation.
What truly matters is not what you see, but how you are guided to understand it.
