At the top I see a lot of American inventors. There are some exceptions. Tesla wasn't born in the US, and classifying Gates and Jobs as inventors is probably a stretch.

Clearly an ML system is not perfectly accurate here! That is known to happen from time to time.

Once upon a time, Google autocorrected "she invented" to "he invented".

It does raise the question though, that bias is in the real-world data. Why should a search engine ignore the real world to paint a happier picture?

It's likely school assignments like "do a paper on an African-American inventor" impact Google's algorithms in that sort of fashion.

Then try googling "us inventors." The difference is that the former appears in the often-used phrase "African American inventors," but I'm not surprised that the right-wing outrage machine that brought us "The War on Christmas" knows its audience is too feeble-minded to figure that out.

You can argue that Google's (and Baidu's and Yandex's) results aren't very good in the former case, and I would agree, but to imply bias intentionally added by the company is to ignore what a search engine does.

Hard to say what's causing this. try "is abortion good or bad" on Google vs Bing and you get very different results. Bing provides evenhanded results and Google is almost entirely pro-abortion.

It's pretty easy to say what's causing this, as I've given the exact reason why and shown two non-US search engines with the same behavior.

As far as your abortion example, Bing very clearly took an editorial decision to put its thumb on the search results ranking, going so far as showing a "vs." with two different articles at the top. Google just let its default relevancy algorithm do the ranking, which means articles that contain both the words "good" and "bad" will tend to rank higher than articles that just contain "bad."

The exact same checks apply to this case to throw out the Google bias argument as right wing outrage hysterics targeted at simpletons who don't know how to verify the assertion. My Google results contain two first page links that say without argument that abortion is bad. Both Yandex and Bing have 0.
