Attribute scores don’t necessarily represent your character’s absolute ability in that area, but how good they are at applying it under pressure. A character can be smart enough to have gotten a top tier education and have a really high Learning, but they can’t solve a puzzle under pressure so have zero Logic.
I’ve seen this argument a lot, and I honestly don’t get it. Sure, given time and resources a logical character can work out a lot, but given time and resources you don’t make the roll in OL. “Every roll matters” and if they have the time to do the research then you just assume that most characters would eventually succeed.
Say that you come across an obscure artifact in some ruins:
Logic you work out some basic information from the object and its surroundings then go do some research based on that. A few days pass as you hunt down old tomes and and work out which experts to question, but eventually you puzzle out exactly what it is.
Learning you already know what it is. As soon as you pick it up you recall the research you’ve previously done. You know that it would be considered sacred to the church in a neighbouring country, and you could sell it to them for a high price. You pocket it and move on.
Alternatively, you meet a local noble and it would be helpful to know who they’re related to; same difference between hours spent tracking down family trees (or risking offense by directly asking) or 30 seconds racking your brain to remember.
You’re given a complex and expensive technological device to gather data on a newly discovered planet; you could spend a bit of time playing with it to logically determine the control scheme, and risk breaking it, or you could just remember having used a similar device before in your lab.
That certainly doesn’t seem “equally good” to me.
