This Fast Company article proves that the humans have given up and are going to allow the robots programmed by marketing experts to eat our brains. It's about The Huffngton Post using an algorithm to decide what headlines stories will run with.
The idea is simple; for the first five minutes that a story is posted, two separate headlines are randomly displayed to readers. the one that gets the most clickthroughs is considered the better headline, and so that one is shown to all the readers after that.
It's true, a headline is important for bringing readers in. A headline is also important to framing an article and informing people who are just browsing the headlines.
Is optimizing clickthroughs the same as optimizing the value to the reader? Reader value is in how quickly and accurately the headline informs the reader. This algorithm only cares about clicks.
We can guess that what gets people to click: sensationalism. Subtly sacrificing value for attention is one of the ways your world becomes dumbed down, replacing expertise with algorithms. I am not opposed to algorithms that attempt to capture, recreate or enhance expertise, but this one cares nothing about value or meaning.
