Trust,information and the web

You don't, in all honestly. This is why it's important to make sure you're getting information from non biased, objective sites. Official sites preferably, such as government based. For instance ... spend any time in prolife/prochoice forums and you'll soon find that many use information from completely biased sources, believing it to be true simply because the website claims it to be. Pro-life advocates quote stats from right to life foundations and stand by them religiously, where a person who wants to be knowledable on the subject would know to go directly to objective sources for their information, not sites run by foundations with an obvious agenda.
