The "low hanging fruit" which you argue Harry ought be researching... they seem to involve organ transplants and the manipulation of dead bodies with "electric transmitters in their mind which mimicked the signal sent when someone cast a test".
Are you serious? How the hell would a first-year student of Hogwarts perform these experiment? How can you call these "low hanging fruit"?
Low hanging meaning that the concept would be fairly easy to come up with, reveal a lot about how magic actually works, and it would be simple to implement. If you can convince a dying wizard who sympathizes with muggles to donate their body to science, the rest is easily within harries means. Also, harry could even test the idea on himself or draco first. If you set up a radio to mimic human brainwaves, tell the wizard to hold onto a wand without casting any spells, and mimic the signal from a wizard casting a spell, you would be able to at least confirm ...
[Update: and now there's a fifth discussion thread, which you should probably use in preference to this one. Later update: and a sixth -- in the discussion section, which is where these threads are living for now on. Also: tag for HP threads in the main section, and tag for HP threads in the discussion section.]
The third discussion thread is above 500 comments now, just like the others, so it's time for a new one. Predecessors: one, two, three. For anyone who's been on Mars and doesn't know what this is about: it's Eliezer's remarkable Harry Potter fanfic.
Spoiler warning and helpful suggestion (copied from those in the earlier threads):
Spoiler Warning: this thread contains unrot13'd spoilers for Harry Potter and the Methods of Rationality up to the current chapter and for the original Harry Potter series. Please continue to use rot13 for spoilers to other works of fiction, or if you have insider knowledge of future chapters of Harry Potter and the Methods of Rationality.
A suggestion: mention at the top of your comment which chapter you're commenting on, or what chapter you're up to, so that people can understand the context of your comment even after more chapters have been posted. This can also help people avoid reading spoilers for a new chapter before they realize that there is a new chapter.
