That last example has interesting implications.
So who on SG1 has the luck perk? Because considering how ridiculous some of things they both get into and survive one of them has to have such a perk. Even when they do get badly injured or killed something heals them which sounds remarkably like that last one struggling to mitigate the sheer danger they are regularly exposed too.
Or is it all of them weakly. Each of them has had lucky breaks when the others weren't around so unless there luck has a second order effect on there friends I can't figure out who it could be.
Also how common are these weak abilities? Historically there actually was a lot of research into psionic powers and magic by respected scientists. Its just after extensive analysis nothing was ever proven hence the derision it is subjected to these days. So either psionics has to be subtle (which is what you seem to be planning), very rare or they should be more accepting of the possibility even if most claims are still false.
A lot of the answers I can give here would be edging into spoilers, so I'll just say think of psychic powers like a three factor radar graph.
Those three factors are Biology, Knowledge, and Soul Complexity.
To get psychic powers someone needs at least fifteen total points on the graph, however which factor those points are in doesn't particularly matter.
Going in reverse, due to the way Souls cycle, at the current point in time it is extroidinarly rare for anyone not previously Ascended to have a Soul complexity above a 2. (Eventus has a 4 here, which of the Ancients knew they would have chalked up to him being multiple versions of the same souls jammed together.)
Knowledge averages about a 1 for humans, a 3 for Asgard, and a 4 for Ancients. (Eventus was born with a 1 but currently had a 5, because he judiciously used the archives.)
And biology averages a 1 for the Asgard, a 2 for regular humans, a 4 for Ancient descended humans, and a 7 for Ancients. (Eventus has a 9 here, which basically put him in the 1 in a 100 group for the Ancients.)
The two big swing points are very much Biology and Knowledge.
Rayla for instance is a 11B, 1K, 3S.
Dia was a 12B, 4K, 2S.
In the interest of completeness, Ascension can potentially occur when those points reach a total of 25.
