Situational awareness and confirmation bias
Situational awareness is more than common sense. However, common sense and emotional intelligence can be vital parts of it. In other words, situational awareness can be simply defined as knowing what is going on in the surrounding environment. As we learned today, situational awareness can be affected by several factors and can result in errors.
One of the most interesting things though in this situational awareness, is the confirmation bias which means that you see what you expect to see and you pick up signals that can support the mental model you've already created, even though the signals may say the opposite. This kind of bias can happen to us any time and I am quite sure that we all have experienced it several times so far.
In fact, this happened to me recently when I submitted a PMA. I was working on it to finalise it for almost two days and after the submission I realised that something was missing. Of course my omission is 'harmful' only for me and the potential mark that the tutor will assign, but when this thing happens in real-life situations where the stakes are higher and human lives can be involved, confirmation bias can have fatal results unfortunately.
