When you fill that out, and submit it, though, you will be shown the source code of the script which was supposed to calculate the results.
To get it to work, download the source, copy it into a .pl file, and upload it to your own server into your own cgi-bin (chmod to 755 before uploading). Then open up the test, use Firebug to edit the ‘action’ parameter of the form to point to your machine, and there you go!
If you want to try it out yourself, my copy of the file is here: http://verens.com/cgi-bin/autistic.pl – go to the wired.com form, change its action using Firebug (“inspect” the form, and click the action parameter to change it), then fill in the form and submit.
I scored 32, by the way, which is not quite the social animal I’m sure everyone takes me for, but also not extremely autistic. (of course, a few of those questions were confusing, so I may have got them wrong 😉 )
