SeventhNadir, are you in Australia? What's an Honours dissertation there? Is it something you do at the end of undergraduate college, or is it a graduate thing? (I apologize for American vocab; I don't know any different).
You do it at the end of a university degree. It is technically an undergraduate thing although it is for most intents and purposes a half sized masters by research. The order goes undergrad degree -> honours -> masters -> PhD except you can skip either or both of the middle two depending on preference, who you know and whether you need a scholarship.
I'm picking a topic for my Psychology Honours dissertation next year and I've got so many options and interests that the overabundance of choice is near paralyzing. So in the interests of crowd sourcing and hopefully writing about something of substance, I'd like to hear suggestions for potential directions I could take. It can be any idea but one that frequently pops up on less wrong and needs further exploration or exposure would be ideal.
Basically feel free to offer suggestions but ideally I want something that (assuming I do it right) would help lay a part of the groundwork required to build up someones rationality.
