AI language models are rife with different political biases

The news: AI language models contain different political biases, according to a new study. Researchers conducted tests on 14 large language models and found that OpenAI’s ChatGPT and GPT-4 were the most left-wing libertarian, while Meta’s LLaMA was the most right-wing authoritarian.

How they did it: The team asked language models where they stand on various topics, such as feminism and democracy. They used the answers to plot them on a political compass, then tested whether retraining models on even more politically biased training data changed their behavior and ability to detect hate speech and misinformation (it did).

Why it matters: As AI language models are rolled out into products and services used by millions, understanding their underlying political assumptions could not be more important. That’s because they have the potential to cause real harm. A chatbot offering health-care advice might refuse to offer advice on abortion or contraception, for example. Read the full story.

Read next: AI language models have recently become mixed up in the US culture wars, with some calling for developers to create unbiased, purely fact-based AI chatbots. In her weekly newsletter all about AI, The Algorithm, Melissa delves into why it’s a nice concept—but technically impossible to build.

The big story

Meet the wounded veteran who got a penis transplant

October 2019

Penis transplantation is a radical frontier of modern medicine: extremely rare, expensive, and difficult to perform. Grafting a penis from a deceased donor onto a living recipient is a chaotic amalgamation that entails stitching millimeters-wide blood vessels and nerves with minuscule sutures.

Ray, a military veteran, lost his genitals in a bomb blast while he was on patrol in Afghanistan—eight years before he got the call to say the hospital had a donor penis ready for him. The procedure would be the most extensive penis transplant ever performed, and the first for a military veteran anywhere in the world. Read the full story.
