UK watchdogs under the banner of the Digital Regulation Cooperation Forum (DRCF) have called for views on the benefits and risks of how sites and apps use algorithms.
Whether that's which video to watch next on YouTube, which film you might enjoy on Netflix, who turns up in your Twitter feed, search autosuggestions, and what you might like to buy on Amazon – the algorithm governs them all and much more.
While that all sounds pretty benign, regulators are hip to the fact that algorithms don't always work for the benefit of consumers.
