Are Google search results biased? Yes

I happened to make a Google search for the expression "don't be that guy" in a browser with no prior search history (which could influence the results), and I noticed a quite clear pattern in the results that the engine gave me. Out of curiosity I also made the same search on DuckDuckGo to compare.

Here's a summary of the first 25 results from Google. For convenience, I have highlighted in bold those results that are not somehow related to "male sexual assault on women":

1. Some website dedicated to sexual assault by men.
2. A The Guardian article about an anti-sexual-assault campaign by the Scottish police.
3. An anti-sexual-assault web page of the Nottinghamshire Police.
4. Another website dedicated to sexual assault by men.
5. The Twitter page for that Scottish police anti-sexual-assault campaign.
