Hmm, maybe the helping your sisters thing (like per the article on Veromessor pergandei rescuing from spiderwebs) really is more rare than I thought?
I had several incidents of Vero pergandei workers coated in sugar. The colony that was slowly dying ("Derpymessor") totally ignored the coated ant, even when I put her in the test tube. My successful colony - well, outworld foragers kind of ignored the ant, but once I put her in the test tube, a nanny ant came over and dragged her further in and other nannies cleaned her off.
Of course, I read the articles like stories of ants doing medical triage to bring home the wounded (posted the article somewhere on Formi) so seeing derpiness can be a little disappointing. But like with my Veros, or with my fraggles where the foragers couldn't figure out fruit flies were edible until a nanny did, maybe IQ varies by ant and only increases after the colony as a whole gains enough members that some of them figure things out.
