*This question is based on my observations.
Q: What is the reason people trust their peers implicitly in extreme (or not) situations?
I am walking with a friend, and I am telling him something. Now we need to cross a road to the other side (not at the crosswalk; we both know that, so this fact is not communicated – we just proceed to the other side) while I am still telling him something. Unconsciously I understand that we are crossing a road at this point, and I am aware of the possible dangers even at that same point when I am thinking about it, but still I do not look to the right or left and continue following my friend, putting my well-being on his shoulders for that moment.
This may not be the worst case scenario and maybe not so extreme, but it is imaginable, and such a pattern is common in many different situations when one person relies on others' awareness of the dangers the current situation possesses without analysing and watching out for such dangers himself, thus dismissing the self-preservation instinct.
