Google Interferes with Its Search Algorithms and Changes Your Results

It's often surprisingly complicated to even find out what people want, even to themselves. And the game is partly rigged against search engines, because people typically don't remember the numerous successful searches, rather focusing on negative experiences.
I do think search engines have a (or numerous) problem, but the solutions are all non-trivial.
[edit] my favorite summary of the problems of fairness in search is the paper "The politics of search" by Laura Granka: https://static.googleusercontent.com/media/research.google.c...
After Obama was elected, a few people noted that the search still worked and a few days later, it no longer returned President Obama or anything like what it did before.
This was all the example one needs to know that your search engine results are heavily manipulated.
This has been a thing for at least a decade and so we can't pretend it's accidental. Why it's still a thing is a matter of opinion I suppose.
