Why are answers sometimes wrong on this site?

Answer 1

Sometimes people purposely answer questions with a bad answer, which is considered vandalism. Sometimes you can research an answer, using multiple websites and come up with slightly different answers on each. Sometimes people answer with what they know, have learned, or have been told by grandpa, and the answer may be technically incorrect, but is actually what they've learned in their experiences. We at WikiAnswers do our best to see that questions are answered correctly, and with hundreds of thousands of wonderful people contributing, it may sometimes take a little while, but we eventually find incorrect answers and correct them.
