Not all the same blind spots - I exaggerated and I shouldn't have.
But in particular, I would expect Bella to have take quite a bit more time to think about the question, will awakening the Quileute really help them? She rightly realizes that the Quileute are in a dangerous and precarious position, but immediately panics and pulls the first lever she can find, instead of thinking for a week or so - or at least a solid hour that the reader sees - about whether that will really make things better.
She should have a pretty significant prior expectation that there's going to be some major consequences to Awakening, given what happens in the closest analogue she's experienced, Turning. A newborn vampire is darn hard to restrain - so why should she assume she has a good chance of experimenting on Rachel without being detected?
She doesn't really strike me as impatient in this way in the first half of the story. I guess it's plausible that the high stakes spook her into uncharacteristic haste, but really, the fact that Aro could "remember" the Quileute at any time doesn't quite imply a "something must be done/this is something/therefore this must be done" kind of response.
Of course, she makes this mistake in her own, distinctive personal style. For example, she does actually bother talking with at least one of the people who would be affected before actually going out there. But two of Harry's most distinctive flaws are Extreme Other-Optimizing and Experimenting Before Thinking, and Bella makes both of these simultaneously by awakening the Quileute.
Actually, it looks to me like that mistake happened because turning shook her out of good habits. She stopped writing journal entries, supposedly because she has perfect memory; but the main benefit of that was consolidating and analyzing thoughts, not preserving them. On top of that, she didn't consult with anyone, because of the mind-reading issue. She thought vampiric super-memory was a substitute for her old cognitive toolkit, but it wasn't, so she ended up doing something very stupid.
This is Part 2 of the discussion of Alicorn's Twilight fanfic Luminosity.
LATE BREAKING EDIT: Part 3 exists now, so new comment threads should be started there rather than here.
In the vein of the Harry Potter and the Methods of Rationality discussion threads this is the place to discuss anything relating to Alicorn's Twilight fanfic Luminosity. The fanfic is also archived on Alicorn's own website.
Here is Part 1 of the discussion. Previous discussion is hidden so deeply within the first Methods of Rationality thread that it's difficult to find even if you already know it exists.
Similar to how Eliezer's fanfic popularizes material from his sequences Alicorn is using the insights from her Luminosity sequence.
The fic is really really good but there is a twist part way through that makes the fic even more worth reading than it already was, but that makes it hard to talk about because to even ask if someone is twist-aware with any specific hints is difficult. The twist is in the latter half of the story. If you are certainly not post-twist and want to save the surprise, then you should stop reading here and fall back to Part 1 discussion or to the fic itself.
If you think you're pretty sure you are post-twist and are safe to read the rest of this, try reading this rot13'ed hint and see if what you've read matches this high level description of the twist...

If the answer to the hint is obvious, then just to be sure that there is not a double illusion of transparency at work, here is the cutoff point spelled out explicitly:
