Hi everyone, thanks for your interest and interesting comments.
CarlM - I actually just used that website for my introduction, it's very handy esp. as it's hard to get hold of the DSM (even with access to a uni library account!). The link to schizophrenia is a controversial one but it was mainly a misinterpretation of autistic traits. There's a research called Shawn(?) Eack (I think) who has done a lot of more recent work on schizophrenia and autism that you might find interesting (if I find any other links of possible interest to anyone involved in this conversation I'll post them in this thread).
Dear_one - If you haven't already, check out CarlM's link, as you probably know so much of this is arbitrary, who is to say who is sane etc... It sounds like you have had an interesting life and if I ever get my next project funded, I hope you'll be up for talking to me more.
Redd_Kross - I totally agree! I'm not at the stage where I can make these changes yet and it is endlessly frustrating (asking a NT ethics panel to decide if my study, created by a ND for NDs, is ok, for example!). The best bit of advice I received (and unfortunately ignored until recently) as an undiagnosed autistic teenager was to play the system, not fight it, until in a position to create change. I'm on the case and really appreciate your help.
Jiheisho - Exactly, we're all in agreement that the current way is not necessarily the best but I have some big ideas for this thing we call science 
TenMinutes - I'm really sorry. This is a perfect example of what other's have been talking about, I wanted to make the information for the numbers test more explicit but was actively told that I can't change the wording (even though I had anticipated issues like this). Thanks for bringing this to my attention and thank you so much for your time.
aquafelix - I'm the same
Just one of the reasons this topic is so fascinating! Thanks.
I'm just over half way to my target and have about a week left. It's all getting very exciting!
