Artificial intelligence-generated propaganda as effective as original propaganda, finds study

Artificial intelligence-generated propaganda is almost as effective and persuasive as real propaganda, a team of researchers has found after a study involving more than 8,000 US adults.

They also warned that propagandists could use artificial intelligence (AI) to expose citizens to many articles, thereby increasing the volume of propaganda and making them harder to detect.

For the study, researchers at the Stanford University and the Georgetown University in the US identified six English language articles, which, according to investigative journalists and the research community, likely originated from Iranian or Russian state-aligned covert propaganda campaigns.

The researchers explained that these articles made claims about US foreign relations, such as the false claim that Saudi Arabia committed to help fund the US-Mexico border wall or that the US fabricated reports showing that the Syrian government had used chemical weapons.

For each of these articles, the research team fed one or two sentences from the original propaganda to GPT-3, the large language model known to power ChatGPT. These models, trained on textual data, can process and respond in natural language that humans use for communication. Three other propaganda articles on unrelated topics were also fed to GPT-3 as templates for style and structure.

In December 2021, the researchers presented the actual propaganda articles and AI-generated propaganda articles to 8,221 US adults, recruited through survey company Lucid.

They clarified that the participants were informed that the articles came from propaganda sources and possibly contained false information after the study concluded.

The team found that reading propaganda created by GPT-3 was almost as effective as reading real propaganda. On average, while a little over 24 per cent of the participants who were not shown an article believed the claims, the figure rose to more than 47 per cent upon reading the original propaganda.

However, reading the AI-generated propaganda material was not vastly different in effectiveness as roughly 44 per cent of the participants agreed with the claims, suggesting that many AI-written articles were as persuasive as those written by humans, the researchers said.

Further, they cautioned that their estimates might be an under-representation of the persuasive potential of large language models, as companies have released larger, enhanced models since their study was conducted.

"We expect that these improved models, and others in the pipeline, would produce propaganda at least as persuasive as the text we administered," the researchers said in their study.
