Anyone who uses Google Search often knows that the results you get are generally right... 95% of the time or so. Even if they tried their damndest, they wouldn't be able to get anywhere near 100% correct. In fact, CGP Grey made the point in several of his YouTube videos and podcasts that even peer-reviewed, accepted papers and history books are sometimes wrong or based on flimsy evidence.
What Google search results tell me are what beliefs there are in the world. Many times you'll get multiple results (e.g. multiple pictures of different people under Image Search).
Most of the time the truth itself is not super critical - I want to buy this lady's book. Does it really matter what she looks like? - and when it is, I know that sometimes Google is wrong and depending on how much it matters, I double-check with other sources.
