Here's the new thread for posting quotes, with the usual rules:
- Please post all quotes separately, so that they can be voted up/down separately. (If they are strongly related, reply to your own comments. If strongly ordered, then go ahead and post them together.)
- Do not quote yourself.
- Do not quote comments/posts on LW/OB.
- No more than 5 quotes per person per monthly thread, please.
It doesn't necessarily follow that it's a highly accurate detector, though. If only a small minority of reasonable people are in this condition, while complete fools are commonly in this condition but their number is still much smaller than this minority of reasonable people, then the above quote would be true and yet your proposed test would be very weak.
A fascinating question would be how strong this test actually is, and how it varies with different subjects.
