Credibility and believability seem to be in completely different ballparks. Something can be believable and not credible, especially if you are talking to a particularly gullible person. Believability is something that is within the realm of reason. While credibility is something solid that can be proven and backed up with facts. Just because I choose to believe something, doesn’t necessarily make it credible.
The text states “just as you would not naively believe a stranger who approached you on the street, you should not automatically believe a site that you randomly encounter on the web.” I love that logic, but there are holes in it. Imagine you are waiting in line at Starbucks and the guy behind you mentions that cinnamon is better for you than nutmeg, you might just believe him and order the cinnamon latte instead of the nutmeg blend. However if a stranger ran up out of no where while you were walking to work and began sputtering about how it was going to rain later and maybe you should have considered an umbrella. You wouldn’t assume he was a meteorologist, instead you would check his credibility by using a trusted resource such as wfaa.com. The same goes for websites.
When you open up a new website the first thing I notice is the layout, but very soon after that I start to read. It doesn’t take long to decide if it looks and sounds legit. When I’m looking a fact up quickly I will often find myself in Wikipedia, which is an awful habit. I read what wiki has to say and then knowing that they aren’t entirely credible I just base my answer off of believability and previous knowledge. Many times I have been given incomplete information from which I drew my own conclusions. Credibility feeds off of believability. Once you believe it you can choose to look deeper or take it at face value.
