I found a similar answer here but it doesn't make sense to me because I found the following on the first page of Google: I found two similar blurbsThese two blurbs seem very similar and when you look at both pages you find that the Princeton page is just a copied version of the first section of the Wikipedia page.Why is Princeton's site ranking?Following the logic laid out in the previous article, how is this possible?Search engines need to penalize some instances of duplicate content that are designed to spam their search index such as:scraper sites which copy content wholesale...Doesn't Princeton's site fall under the scraper sites mentioned in the other explanation of how Google penalizes duplicate content?Here are the two links:Princeton PageWikipedia Page
How does Google penalize for word-for-word copied content and aggregation?
google;duplicate content
The Princeton copy is not a full copy of the article and still falls within the parameters of Content Syndication on the page you linked to:  What is duplicate content and how can I avoid being penalized for it on my site?It does give full credit and links back to the original as suggested in the Content Syndication section.As to why the Princeton page ranks so high in the SERPs? Likely because Princeton enjoys significant rank and trust in general. The page does not appear to be spammy which is what Google's concern is.Is this page scraped? No. I doubt it. I am sure it was a manual attempt. Cut and paste? Yes. Scraped? No.
