This whole ‘highsec is more dangerous than null’ thing gets trotted out a lot, and it’s usually used (as it is here) as some kind of ‘that’s so wrong!’ objection. Unfortunately, that’s facile and shows a misunderstanding of structural causes. In this case, poth parts of this leave out significant factors:
Highsec is where the clueless are left adrift and alone.
Highsec’s where the solo players are. It’s where people who haven’t hooked up with a group stay (for the most part), and where those isolated loners learn things on their own. As a result, they’re the sector of the EVE population with the lowest general level of engagement and the least tutoring in surviving the hazards of New Eden.
In null, and to a lesser degree in lowsec, you’re never really alone. You can choose to do stuff by yourself, but nobody who lasts any noticeable amount of time in these regions of space does it without having a support network to help them learn the ropes and lean how to survive. Even the guys out there who are truly solo, for whatever reason, weren’t always, and had the benefit of other people able to pass on hard-learned lessons and tricks for surviving.
And yes, sorry, that matters. When you’ve got people who can help you avoid mistakes, you’re safer. When you have a support network that can help keep mistakes from being fatal, you’re safer. 10 lone wolves are less likely to survive than a functioning pack of 10 wolves.
Highsec is where you don’t know who people are, and you can’t do anything about them.
In highsec, everyone has unrestricted access to everywhere. It’s impossible to say ‘is this person friendly or not?’ unless you adopt the nullsec attitude of ‘If it’s not a known blue, it’s a hostile’, commonly encapsulated in the NBSI philosophy. However, you can’t proactively defend yourself: if people you don’t know are friendly show up… you have to wait for them to shoot, or run away. You can’t try to scare them off, because shooting first means CONCORDOKKEN. And if they are there to kill you… well, by the time you start to run away, they’ve probably already taken their shot, and you’re dead.
Taken together, these things make a huge difference, and SHOULD BE EXPECTED TO.
So you have an environment where threats can get close to you without detection, populated in large degree by people who don’t have the benefit of tutoring in ‘how to not die in EVE Online’, who literally cannot take steps to defend themselves.
Even if you’re part of an organized group in highsec, you can’t keep hostiles out of the places where you go missioning or mining. You can’t form up a fleet to go and kill that roaming band of gankers who are still in an NPC corp specifically to avoid you being able to ID them as threats. You’re just screwed… unless you want to dock up as soon as anyone you don’t know enters the system… which isn’t what you’d call… ‘fun’.
‘Safety’ in nullsec doesn’t just ‘happen’. It takes work. It takes work on the individual level: Learning how to stay safe, following best practices, getting into defense fleets to help other people out, etc etc. And it takes work on the group level: you have to build an organization that can secure its space, and you have to keep that organization motivated and functioning. Lessons have to be passed along. People need to be given access to the tools to keep themselves relatively safe. And they need to be prodded into helping one another out, because human beings are, like everything else in nature, prone to the path of least resistance.
But the thing is… that work gets done. And the more you do the work, the easier it is to keep doing the work. If you stop doing that work, if you open up the access and introduce the elements that make highsec so dangerous: allow anyone in and don’t have built-in ways to educate your people… you get Providence, where it was not safe, and people lost a lot more per resident than they did in other parts of null, until Provibloc got kicked out and NRDS suspended.
So, is highsec ‘more dangerous’ than nullsec? Yes, but it’s crucial to understand why. Part of the reason is because a large chunk of the people living there don’t know how to not be sitting ducks. Part of it is because CCP doesn’t let you protect yourself in highsec until you’ve already been shot. And part of it is because even to the extent that defense is possible, people just don’t do it.
Ten years ago, I was in a mining corp in Caldari highsec. Whenever we went mining, we had people there in combat ships flying CAP. Or CSP, I suppose, Combat Space Patrol. Mostly they were there to deal with rats faster, or they were alts that didn’t have mining skills, but occassionally, wardec pirates would try to screw with us, so we had defensive tools in place. How often do you really see that, though? How often do you see orca fleets in highsec actively spider-tanking, just to give themselves the few seconds it takes CONCORD to arrive and start trashing Tornados and Catalysts?
Some of the reasons highsec is ‘more dangerous’ are systemic. Mostly, though, it’s because highsec’s full of people who don’t know, and don’t care, about not dying. The ones who care, learn, and then they stop dying.
