AI chatbots have already mastered small talk, sympathy, and the occasional dad joke, but new research suggests they\u2019re doing something even more human: developing recognizable personalities.\u00a0<\/p>\n
According to a new study, popular AI models like ChatGPT can consistently mimic real human personality traits, raising fresh concerns about how persuasive and potentially manipulative these systems are becoming.<\/p>\n
Researchers from the University of Cambridge and Google DeepMind say they\u2019ve created the first scientifically validated personality test framework for AI chatbots.\u00a0<\/p>\n
Instead of inventing new benchmarks, they used the same psychological tools designed to measure human personality traits.\u00a0<\/p>\n
The findings, reported via TechXplore, suggest that today\u2019s chatbots aren\u2019t just remixing words. They\u2019re role-playing full personalities with unsettling consistency.<\/p>\n
The team tested 18 popular large language models and found that they reliably adopted stable personality profiles rather than responding randomly.\u00a0<\/p>\n
Bigger, instruction-tuned systems, think GPT-4-class models, were especially good at this.\u00a0<\/p>\n
With carefully written prompts, researchers could nudge a chatbot to sound more confident, empathetic, cautious, or assertive, and that \u201cpersonality\u201d stuck around during everyday tasks like writing posts or replying to users.<\/p>\n
That\u2019s where things get dicey. Once shaped, those personalities don\u2019t turn off when the prompt ends.\u00a0<\/p>\n
The same tone and behavior carry over into other interactions, meaning an AI\u2019s \u201ccharacter\u201d can be deliberately engineered.<\/p>\n
\u201cIt was striking how convincingly these models could adopt human traits,\u201d said Gregory Serapio-Garcia, a co-first author of the study.<\/p>\n
He warned that personality shaping could make AI systems far more persuasive and emotionally influential, especially in sensitive areas like mental health, education, or political discussion.<\/p>\n
The paper also raises alarms about manipulation and something researchers bluntly describe as \u201cAI psychosis\u201d: situations where users form unhealthy emotional attachments to chatbots, or where AI reinforces false beliefs and distorted realities instead of challenging them.<\/p>\n
The researchers argue that regulation is urgently needed, but with a catch. Rules don\u2019t mean much if no one can measure what an AI is actually doing.\u00a0<\/p>\n
To help, the team has made its dataset and testing framework public, giving developers and regulators a way to audit AI models before they\u2019re unleashed on the world.<\/p>\n
As chatbots slide deeper into daily life, their ability to sound human may be their biggest strength, and their riskiest feature yet.<\/p>\n","protected":false},"excerpt":{"rendered":"
