1) If we are interested in autism quotient, I suggest adding RMET because, while not a direct measure, it's also not a self-report.

On that note, why all the focus on autism, and not generalized mental illness?

I suggest adding the most common Axis I and II disorders as listed here and asking people to specify [No] [Suspected but un-diagnosed] ][Yes, diagnosed]. If size is a constraint, I'd suggest just doing Axis I with a write-in option.

For ease of access:

Axis I: depression, anxiety disorders, bipolar disorder, ADHD, autism spectrum disorders, eating disorders, schizophrenia.

Axis II: paranoid personality disorder, schizoid personality disorder, schizotypal personality disorder, borderline personality disorder, antisocial personality disorder, narcissistic personality disorder, histrionic personality disorder, avoidant personality disorder, dependent personality disorder, obsessive-compulsive personality disorder

2) You can use this to quickly implement a drop-down menu listing every country for your country question

3) Singularity question seems ill-defined, due to many different definitions of "singularity". Maybe replace with something specific? (Strong AI, sudden intelligence explosion, etc)
