Actually, there is a lot to learn from sciences, that can help testers to be better in their job. I’m focusing on inattentional blindness here.
By definition inattentional blidness is the failure to notice a fully-visible, but unexpected object because attention was engaged on another task, event, or object.
How many times have you been browsing through the software you’re testing and missed an obvious bug? How many times have you felt that you should have noticed the issue that was reported by someone else?
