Frankly, I'm not quite sure how Akiko's brain damage could've been revealed through scouting, and that's the main thing that tripped us over. Hell, we even interacted with her directly, and we didn't pick it up at all, and even with hindsight I don't see how we could've positively determined the extent of her brain damage in advance. There's also the fact that alot of the conflict has it's base in the clash of personalities, and those aren't things that we could find out without interacting with the participants directly.
