First of, you need to factor in all the noobs that start the game, run somewhere, shoot zeds, die at some points yet never run into a player. On a not-so-populated server and even on a populated one, if you don't go into chern or electro because you don't know the map (like probably 80% of players do) you will walk for an hour or longer till you reach your first player. Since average life expectancy is lower, most people won't ever have the chance to decide if they are bandits or not. Survivor doesn't mean he is friendly, it can also mean in his average short life span he didn't run into a player. People die often before they see another survivor or got a weapon to hurt him. So in reality, if you factor in people that spawned with no weapon and people that died before meeting someone else with a weapon you can likely double that number or increase it to 60% or more. Pure speculation though. Average life expectancy is 40 minutes, I now played for several hours, only saw a person once. I started with looting cherno and looked into every big city by now except stary or the airfield. Does a bandit kill count if you kill another bandit? Bandit skin has been removed, but humanity is still there (invisible to us) as far as I know. This could also change numbers significantly. Now lets estimate that the numbers would be only 20%. DayZ would still be pretty much a deathmatch to all the people posting here and playing the game a lot. You want your character to not die. If you trust others and your chance of meeting a bandit is 20%, after only 3 encounters with other players your chance of "not" being shot by another player is roughly 50%. Your chance of survival in every encounter if you trust the other player is 80% (chance that the other player is friendly). 3 times is 0,8*0,8*0,8 ~ 0,5 So while a 20% chance doesn't sound like a lot, it absolutely prohibits any other policy then avoid or shoot on sight if you want to survive for a long time in this game. If you decide to go up to other players and you meet 5 players that day, you are most likely dead. The 20% of bandits would make coop pretty much impossible if you want to survive over a day. If you had in reality a 20% chance of getting killed by walking across the road, you would avoid it because you knew if you walk across it every day you won't reach the end of the week even if this single time it may work. You'd avoid it entirely.
