Enter critical thinking. If you dig just a little (e.g. read the talk pages and the edit histories), you can soon learn that some topic has been taken over by POV-pushers and is unreliable. Anything to do with Israel/Palestine/West Bank is unreliable; the boss is a zionist, and so are a lot of the senior staff, so it's not surprising. But WP is a million times better than the web that search engines expose.
Incidentally, I usually search using DDG. But DDG seems to hate Wikipedia; WP results usually don't show up on DDG until page 2. Google surfaces WP results on page 1, if not at the top of the resultset.
