Wikipedia:Tip of the day/tip one

Don't believe everything you read

As anyone can edit any article, it is of course possible for biased, out of date, or incorrect information to be posted to Wikipedia. However, because there are so many other people reading the articles and monitoring contributions using the Recent Changes page, incorrect information is usually corrected quickly. Thus, the overall accuracy of the encyclopedia is improving all the time as it attracts more and more contributors. You are encouraged to help by correcting articles, validating content, and providing useful references.

If it is obvious an article has just been vandalized, you can revert it yourself or refresh the page and wait for someone else to do that for you. Most obvious vandalism is reverted very quickly. Read more: Researching with Wikipedia
