False information has existed for as long as people have communicated, but the internet has given it remarkable new power. Studies of social media have found that false stories often spread faster, reach more people, and travel deeper through networks than accurate ones. One large analysis of millions of posts concluded that lies were far more likely to be shared than the truth, and that this held true across every category of news the researchers examined. The finding alarmed many experts, who had once assumed that automated accounts, or "bots," were mainly ( 1 ). In reality, ordinary human users were doing most of the spreading, passing falsehoods on to friends and followers who trusted them.
Psychologists offer several explanations for this pattern. False stories are often deliberately designed to be surprising, and novelty naturally attracts human attention. They also tend to provoke strong emotions such as fear, anger, or disgust, and emotional content is shared far more readily than calm, balanced reporting. ( 2 ), people frequently pass on headlines without ever reading the articles beneath them, trusting a claim simply because it fits what they already believe. Once a piece of false information matches a person's existing opinions, correcting it later becomes remarkably difficult.
Researchers are now testing practical ways to slow the spread of falsehoods. One promising approach is called "prebunking," in which people are shown in advance how misleading tricks work, before they ever encounter them, rather than being corrected only afterward. Brief on-screen warnings that simply encourage users to pause and consider whether something is accurate can also reduce careless sharing. Such methods will not ( 3 ) the problem on their own, and no single solution is likely to. Yet they suggest that even small changes in how information is presented can make a real and measurable difference.
(1) 正解 1. to blame
後続文で「実際はふつうの人間の利用者が拡散の大半を担っていた」と続くので、研究者が以前「主に〜だと思っていた」のは『犯人だ(to blame)』が自然。
(2) 正解 2. Furthermore
段落は誤情報が広がる理由を列挙しており、空所の後も新たな理由を加えている。情報を付け加える Furthermore(さらに)が正解。
(3) 正解 1. eliminate
but 以下で「小さな変化が効果を生む」と前向きに続く一方、空所文は「問題を〜しはしないが」と限界を示す。eliminate(根絶する)が正解。
