One wonders both what motivations and possible evolution bases# there are for both corporate and social media respectively to shape, amplify and reinforce moral panic memes like "terrorists posing as immigrants," "software criminals," "evil corporation [when portrayed as a monolithic, malevolent being]," InfoWars conspiracy theories, etc. Brainstorming quickly: there's obviously profit-motive (in for-profit media: clicks), agenda (where not minimized by editorial review), influence brownie-points (ie likes, shares, other metrics), envy of unattainable status (ie lottery winners, high-paid engineers, caste, etc.), in-group values-reinforcement tribalism (ie hating on changes) and ongoing infatuation with topics that don't have a conclusive resolution (ie MH370, etc.). But what are some other motivations? (#All your "basis" (plural) are belong...) EDIT: There's also spinning up unsubstantiated tall-tales to reinforce prejudices. Gotta love social Darwinian pressures to eliminate potential "rivals" / competition for "limited" resources.
