I've noticed that the vast majority of people (in my experience) when walking into a room or through an area (ie. in school or work) are almost tunnel visioned on what lies directly ahead of them... like just getting from point A to point B... so if they were walking down a road they would just be looking straight down the road, not paying attention to the background or ever looking side to side. I've noticed in my experience that only a few people will look at the people around them. I would like to know what everyone's hypothesis is on: why so many people don't (or why more people don't) pay more attention to their surroundings... like when they enter a room... look at all the objects or people in it (more than a super quick automatic glance or peripheral vision), when studying in a study area, why don't they look at the people around them more frequently? When someone or something new (that's not being obnoxious) enters their area/room.. why not look at it? Why not pay more attention to the changing scenery (outside of nature trips lol) when in populated environments?

It almost seems like these people are self-absorbed and primarily focussed on themselves/what they're doing/what they need to do/their path/their thoughts. This may sound harsh, but I'm not judging them... I don't know what's going on in their life or how they developed or anything, I'm just coming from a place of curiosity because I've noticed sooo many people do this, regardless of their personality (ie. narcissistic vs. altruistic). Although I have noticed that the more altruistic people are the more attentive they seem to be to the people around them, so I guess that sort of contradicts my example lol. I've also noticed that the frequency of this behavior seems to almost be inverted when it comes to driving, with the majority of people constantly looking into other cars and people along the sidewalk (especially during traffic).

Below is some background information for purposes of comparison/contrast and context. I know that the following is outside the norm and likely stems from my own things such as ADD/ADHD and my childhood epilepsy's impact on by brain or whatever.

Whenever I'm studying or going about my day in general I seem to be very reactive to my surroundings when something new is introduced. For example: if someone enters the room (ie. auditory stimulus) or my field of vision (visual stimulus), or I enter a new room filled with people or objects... I scan the room/people/objects (usually repeatedly) and if anything catches my attention/curiosity or provides further stimuli than I obviously end up paying more attention to it. Sometimes this can be for a couple of seconds or even lead to me zoning out for up to 30 seconds... even to the point where I'm not even paying attention to the room/person/object anymore and more-so just in a sedated trance (but still aware of stimuli around me, it's just like I'm too sedated to respond to it right away).
