Why it matters for marketers

What happened

A meta-analysis of 19 studies, posted in April and peer-reviewed in August, found that using AI tools makes people's ideas, designs, and writing more similar to one another. The effect is small, and the authors describe it as a gradual reorganisation of creative diversity.

In August, a study in Nature Human Behaviour of more than 880,000 texts found that rewriting them with language models cut the variation in how complex they were by between 21% and 50%. Earlier research found that Indian participants writing with AI suggestions drifted towards Western styles.
