    its value is still considerable, of course -- there are far more neutral things than controversial ones, and most of the articles about those are fine

    one of the more neutral point-of-view sources on the internet these days given its wide range of editors and consensus process

What people warn about

  • Ideological bias on politics · 4

    I hesitate to use Wikipedia as a source given all the anti-Israel bias lately, but that particular section seems okay-ish for now

    Nov 2025 · comment

    Wikipedia is ideological. Even when the articles stick to the facts (which they often don't), editors will selectively omit inconvenient (but factually true) information to push their ideology.

    May 2026 · comment

    Unqualified people have the power to tell experts who were there that their contributions are insignificant, wrong, or that details don't matter.

    Jan 2026 · comment

  • Inaccurate on expert topics · 3

    I find wikipedia is really vulnerable to Gell-Mann Amnesia where any article about a topic on which you are very familiar has blatantly incorrect information
