If you change the question to “what are the highly selective liberal arts colleges?” does that better get at whatever you are trying to shorthand for? I imagine you are trying to find the group at more like 15%ish or less admissions rate rather than 40% or less. This thread is a bit challenging because it’s not clear what you are trying to achieve. Also, if true that if you search for a LAC like Occidental, or Lewis&Clark or St. Olaf or Centre College and AI is telling you whether or not it’s a “little Ivy” that seems more a sign of the uselessness of the AI answers than anything else to me.
