Understanding how digital platforms transformed the speed, scale, and structure of information flows in modern societies.
Flashcards combined with spaced repetition improve active recall. You review at the right time, retain knowledge longer, and track progress card by card.
Card 1
People started discovering news passively while scrolling rather than actively seeking it.
Explanation
Social feeds turned news discovery into a background activity that appears alongside entertainment and personal updates.
Common mistake
Thinking people on social media always make a conscious choice to look for news content.
Card 2
Posts appear strictly in the order they were published.
Explanation
Chronological feeds prioritize time, while ranked feeds reorder posts based on algorithmic relevance signals.
Common mistake
Assuming a feed that “shows everything” must automatically be chronological.
Card 3
Ordinary users became regular publishers of information to wide audiences.
Explanation
Publishing is no longer limited to media organizations; anyone can contribute to the information environment.
Common mistake
Believing user-generated content is automatically less impactful than professional media content.
Card 4
Public sharing makes posts visible beyond direct contacts, often to the general platform audience.
Explanation
Public posts can circulate widely through search, hashtags, and recommendations, unlike private messages.
Common mistake
Assuming that removing someone from your friends list automatically hides all your public posts from them.
Card 5
Audiences can rapidly redistribute content among themselves, not just receive it from a central source.
Explanation
Many-to-many sharing creates dense sharing networks where users influence each other’s information exposure.
Common mistake
Equating many-to-many sharing with simple one-to-one private messaging only.
Card 6
It reorders available posts to show what the system predicts you are most likely to engage with.
Explanation
Ranking systems prioritize content predicted to capture attention, shaping which posts become visible first.
Common mistake
Thinking the algorithm simply hides posts at random rather than following engagement-driven logic.
Card 7
They infer your interests from previous actions to decide what to show next.
Explanation
Clicks, likes, watch time and similar signals help algorithms predict which future content you may prefer.
Common mistake
Believing personalization mainly relies on reading private messages rather than observable engagement.
Card 8
How much time users spend viewing a post or video.
Explanation
Watch time or dwell time indicates attention, so algorithms often boost content that holds users longer.
Card 9
It reaches you because the algorithm predicts relevance, not because you chose to follow the source.
Explanation
Platforms expand your information environment by inserting posts from accounts you never explicitly selected.
Common mistake
Assuming all items in your feed come only from people or pages you decided to follow.
Card 10
Interacted-with content gets shown more, leading to more interaction and even greater visibility.
Explanation
This loop can amplify particular narratives simply because early engagement signals were strong.
Common mistake
Thinking algorithms treat every post equally regardless of how users initially respond.
