If you type "Rizaeddin bin Fakhreddin" into Google, Google will give you a list of links and a small box to the right. The first link will probably be to the English Wikipedia article on bin Fakhreddin, created and written by me; this can easily be checked by going into the page history of the article. But most likely you'll never bother to actually click on the article because of that small box to the right. "Rizaeddin bin Fakhreddin was a Tatar scholar and publicist that lived in the Russian Empire and the Soviet Union", it reads.
I typed that sentence. I also put the birth and death dates onto Wikipedia. I uploaded the picture to Wikimedia Commons and put it into the article – or articles, actually, because I also created the article on the German Wikipedia. But now I find this information directly on Google. There is a link to the Wikipedia article, but that may as well be a result of Father Google's omniscient mercy. Nowhere does the box state that it presents the work of an unpaid volunteer next to Google advertisements. The effect is obvious: In a 2017 study, half of the participants attributed what they found in the Knowledge Graph, which is the name of that small box, not to Wikipedia, but to Google.
