Post-Heth, don't most Caldari have some sort of mandatory military training? I'm not sure the State necessarily imposes mandatory enlistment terms (need to reread TEA, and I will never, ever do that), but I wouldn't be surprised if different megas do have some sort of 'militia' element, in addition to basic drill during education/upbringing. I'm not sure there's any equivalent for Minnie, Gallente, or Amarr-- though I'm sure that most Amarr capsuleers are noble or wealthy, which implies either only ceremonial use of arms or none at all.
That said, with skills being loleasy for the first few levels, it'd be easy to see, say, 'security connections' including engrams for basic military drill. But yeah. Meh. I think there's an automatic assumption of Capsuleer = badass = guns, lots of guns a la Keanu Reeves.
A nifty idea: what about additional paranoia about baselining? Even with softclones, capsuleers exist in a world where suicide ganking is not only possible, but a frequent happening, a profession. Translate this to real life-- where if you're walking down a busy street, someone catching a glimpse of your wallet or shirt may go, "WORTH IT," and shoot you in full sight of the police.
