Machine learning and choice paralysis: How Netflix personalizes title images

The visual cortex takes up 30% of the human brain, so people naturally process images 60,000 times faster than text. As a result, we're all guilty of judging books by their covers, which is a crucial element of Netflix's engagement strategy. Netflix has a seemingly unlimited supply of content, which can be a double-edged sword. That volume of content produces choice paralysis, where people have so many options that they can't decide what to watch. "We don't have a product. We have hundreds of millions of products because we deliver personalized experiences," says Tony Jebara, Director of Machine Learning.
