Tom Scocca, writing for Gizmodo:

A little under five years ago, I got angry about a piece of fake information, and I decided to do something about it. I was reading a recipe in the New York Times, and the recipe told me, as many, many recipes had told me before, that it would take about 10 minutes of cooking to caramelize onions.

I knew from personal experience that this was a lie. Recipes always said it took 5 or 10 minutes to caramelize onions, and when you followed the recipes, you either got slightly cooked onions or you ended up 40 minutes behind schedule. So I caramelized some onions and recorded how long it really took — 28 minutes if you cooked them as hot as possible and constantly stirred them, 45 minutes if you were sane about it — and I published those results on Slate, along with a denunciation of the false five-to-10 minute standard. […]

Not only does Google, the world’s preeminent index of information, tell its users that caramelizing onions takes “about 5 minutes” — it pulls that information from an article whose entire point was to tell people exactly the opposite. A block of text from the Times that I had published as a quote, to illustrate how it was a lie, had been extracted by the algorithm as the authoritative truth on the subject.

There are quite a few examples of how Google’s massively dropping the ball with their “one true answer” feature.
