Some people believe everything that they read or are told. They take the information they are provided with and accept it to be the true.
In this day and age the people in power would love us all to act like this and follow what we are told without even considering that we are being lied to. If you are skeptical about a particular subject or story that you have heard about in recent times and would like to learn more about it, then you might like to take a look at a web site called www.skeptically.org. This site lists links to other web site and stories relating to a wide range of different subjects, from the war in Iraq to politics, medicine, theology, mortality, miracles and a whole lot more. The web site itself is a little disorganized, but if visitors are prepared to take a little time scrolling down the main page they are sure to come across a link to the particular subject that interests them.
