I'm not sure if this is Devil's Advocating or not, but let's think about this.
We say nearly everyone has martial arts training and / or is a gun freak or whatever.
Again I point to the 2 circles. I'd draw them if my mouse skills weren't so abysmal, but there 'the people who RP' and 'the people who do not'. This cross section of RPers is a small section of the first much smaller circle. We still fly through space
drowning in the people in the second circle (they're not all bots or something. I know, I've been in non-RP corps. 'What is RP?' they ask. 'Is that that sex thing?')
Their characters aren't martial art experts. They never get out of their capsules from an RP standpoint. They're the factions and CONCORD's favorite kids specifically because of that. In there they can stay under control.
Anyone willing to get out of their Capsule and baseline against the rules or social mores that are present in most every faction (even if a Capsuleer is able to mingle with people in the Republic, social mores would keep them in their ships, fighting, Gallente wandering around likely have more than just their personal bodyguards mixed in among the cameras and glamour, Caldari are strictly segregated by way of highly accurate ammunition and seperate station areas, Amarrians are looked at with this odd twisted mix of awe, fear, sadness, and possibly disgust). This would leave any Capsuleer who wants to be out and about dealing with quite a bit of space paranoia on the ground. EVE paranoia is far reaching.
Could implants or SOCT training enhance this? Muscle memory? Tee-hee. Cloning makes REAL memory. Muscle memory is probably a joke to do. As it is we're born as cloned adults. Do we need to learn to walk again To run? To talk? To laugh, cry? Nah. Those are also muscle memories. Grimdark dictates we are dumped on a grate in a spash of golden hydrostatic fluid, and we also walk up right behind each other and put a bullet into each other.

Will experts tend to run into each other in a way that feels 'tropey' and 'more often'? Yes.
Why?
Because Fiction.
Also, because we've in a sense been actively seeking eachother out. Want to mix fantasy and reality? Go the entire nine yards. What made your character look for "other people who don't babble and call me weird slang names all the time"? Wouldn't that be, erm, dangerous? Wouldn't you be concerned about defending yourself? Capsuleer Paranoia and all that?
