This visual guide is excellent. Believers ought to study up on these biases and apply them to their faith just to help conduct an objective study of why they believe. If someone had the time to cut and paste these biases from page 9 onward, I would be grateful. Follow this link then at the bottom there are arrows to turn the page. You might want to click on "Full Screen" icon too. [Hat Tip to Luke at Common Sense Atheism].Look very carefully at this list:
I think anyone should realize that we do have biases. But just because you have a bias does not automatically make you wrong. What people like John Loftus should ask themselves what biases do they themselves have and honestly consider if their biases have blinded them to the truth. I would also say that just because someone disagrees with you does not mean that they have not examined themselves. I realize that many atheists have done this exercise. The thing is how can you even hope to judge rightly without God?
