Don’t need 5 studies. Just look up anything political over there.
As I understand it, you can make a Wikipedia entry about yourself or about anything, say what you want. No fact checking.
I may be wrong. If so, tell me.
The fact checking is done by others who read the article, theoretically by everybody in the world. Over time that should lead to greater and greater accuracy, assuming good will and a lack of bias.
Of course, that can’t be assumed, and what happens with controversial topics is that people with different biases struggle to make their version prevail. Still, if you have good evidence, there’s a chance that there will be enough fair and intelligent persons participating in writing the article that your contribution will be accepted. That’s a better chance than you have with a story in the mainstream media.
