Yes Yes We get more answers right than wrong. The wrong answers are part of the fun, we get to be smarter than the people who give us wrong answers and correct them. Keep in mind, many times you find a wrong answer, it is from some bored kid in computer class just vandalizing the site because he/she has nothing better to do. You could do your part and come in to give some good answers on subjects you are really smart at.
There are a few reasons why Answers.com will give the wrong answers. There are people who vandalize this site. Some people just have nothing else better to do than to ruin the experience of the people who are actually looking for answers. Others don't do their research correctly, or get their answers from the wrong source. Supervisors try very hard every day to clean this site up. Those are some reasons why Answers.com may give wrong answers.
The main reason is because this is a wiki site. That means that any contributor can give answers, even wrong ones. Some deliberately give unhelpful or wrong answers, but most simply think they know the answer when they don't.
some people on wikianswers think it is funny to put in wrong answers. we have supervisers that find bad answers and make them right.
