Search for 'white man and white woman.' The reason I mention this is that the article implies this is some sort of result of social bias and stereotyping. As the result of that search shows (it's entirely interracial couples), it most certainly is not. No, it's a result of the fact that Google's search is not particularly smart. It's arguably the best there is, but it still comes down to correlating words to pages and that correlation is far from intelligent.
And as an aside, I think the term of bias in algorithms is misused when they are operating as intended. You'd call a poll biased if it implied it was polling group 'x', but did not actually do so due to some inadvertent bias. You wouldn't call it biased if it polled the group it stated it was going to poll and then gave the results - even if those results were not what you personally would want to see. If people are mostly searching for interracial couples when they search for 'white man and white woman' or they are mostly searching for porn when they search for 'black girls' then a biased algorithm would be one that actually returned white couples or non-pornographic results.
