Bias in AI amplifies our own biases, finds study

Artificial intelligence (AI) systems tend to take on human biases and amplify them, causing people who use that AI to become more biased themselves, finds a new study by UCL researchers.

Like humans, artificial minds can learn by thinking, review shows

Some of the greatest discoveries don't come merely from observations but from thinking. Einstein developed theories about relativity through thought experiments, and Galileo derived insights about gravity through mental simulations.
