google searches do the same. They don't just match your words to the most common sites out there, their search algorithms are massive and constantly changing, dozens of people working on them alone. They base their searches on what you've previously searched for, read, opened anything... all those cookies on your computer feeding google to try and best match what you are looking for. Which is fine if you want a fleece jacket for winter, but not so good if you want to learn something new. If you google for information, it's likely to be confirming your thinking, not expanding. Conformation bias as they say. The only solution, share you computer with someone who is the polar opposite to you in all respects.
