It’s not just search engines that are powered by artificial intelligence. From the courts to the jobs market, AI is influencing decisions that have a big impact on people’s lives. But researchers now believe that not all people are treated equally by some algorithms. They’ve found potential bias - influenced by race, class and gender - can have an impact on the decisions that computers make. Some programmers, computer scientists and entrepreneurs hope to fight this bias, using the technology that created it in the first place. Produced and presented by Craig Langran Image: Getty Images
