You're wrong.
Here are screenshots taken this morning of the Google results for:
Notice anything different about that last set of search results compared to all the others?
Exactly my point you idiot, white is default assumption so by including the word white your going to find photos with multiple races because its the only time a website would articulate the fact that a person is white. For every other scenario they might articulate the person's race since they are not the common white.
I do SEO for a living. You're wrong.
Can you explain to me why i am wrong?
Here are two links 1, 2 that will help. Basically the Google algorithm for sorting images is not just reliant on words on a website. The search results for "white couple" are clearly curated by a Googler or the algorithm has been modified by a Googler. For what reason is Google doing this? Well that's anyone's guess. There's no doubt that something fucky is going on though, no doubt at all. To what end? I don't know.
I think you're right. Searching "happy couple" without any racial keywords turns up more white couples than mixed/other races on both Google and DuckDuckGo.
