In the days since the war between Israel and Hamas erupted, false information and misleading videos have flooded social media platforms, making it difficult for readers to sort fact from fiction. Footage said to depict a Hamas militant paragliding into Israel was in fact taken in June, during an incident in South Korea. A graphic video posted to Facebook was not of an Israeli hostage burned alive, as one user claimed, but the lynching in 2015 of a 16-year old Guatemalan child. A clip allegedly showing Israelโ€™s Iron Beam air defense system wasnโ€™t from a real event at all, but from the video game โ€œArma 3.โ€

โ€œAn algorithmically driven fog of warโ€ โ€“ thatโ€™s what tech reporter Ari Ascher Shapiro, speaking on WNYCโ€™s On the Media, called the problem. Itโ€™s an update of a phrase attributed to 19th-century Prussian general and military theorist Carl von Clausewitz. โ€œWar is the realm of uncertainty,โ€ he wrote. โ€œThree quarters of the factors on which action in war is based are wrapped in a fog . . . . โ€ 

Clausewitz fought in the Napoleonic Wars, when the phrase โ€œfog of warโ€ would have evoked thick plumes of black gunpowder on the battlefield. It is easy to imagine โ€œfogโ€ referring to the lack of information military leaders and soldiers would have had about the strength and position of the enemy. But recently, scholars have argued otherwise. โ€œHis famous metaphor,โ€ writes historian Alan Beyerchen in the journal International Security, โ€œis not so much about a dearth of information as how distortion and overload of information produce uncertainty as to the actual state of affairs.โ€ 

Thatโ€™s much closer to todayโ€™s โ€œfogโ€ on social media, a result not of too little information, but too much of it, with no reliable way of instantly determining its accuracy. This fog has infiltrated, in real time, the highly politicized, high-stakes debate over the war between Israel and Hamas. 

โ€œIโ€™m so angry about how impossible it is to tell whatโ€™s real or fake on this site anymore,โ€ NBC News senior reporter Brandy Zadrozny said on X. โ€œThereโ€™s nowhere else to go so we all just stay here and act like anything is reliable.โ€ Under Elon Musk, X, formerly known as Twitter, has made deep cuts to its content moderation staff. Meta, which owns Facebook, has reduced the number of news articles that appear in usersโ€™ feeds. These changes have made it โ€œclose to impossibleโ€ for researchers to track all of the war-related misinformation and violence on social media platforms, Rebekah Tromble, director of George Washington Universityโ€™s Institute for Data, Democracy and Politics, told NBC News. 

The risk of encountering false information hasnโ€™t limited usersโ€™ willingness to wade into the increasingly fraught debate over the war, but it might give them the pretext to believe whatever they happen to agree with, and disbelieve what they donโ€™t. 

โ€œPeople are turning to sources that mirror their feelings,โ€ Steven Lee Myers wrote in a news analysis in The New York Times. โ€œThere are so many untrue claims that some people question the true ones.โ€
