Amos, you're right, that would be an interesting study.
Are there other characteristics that are co-varibale with reliable receipt and forwarding of human messages?
The only result I remember (and of course I would be likely to remember such a result) is that skeptics are much more likely to correctly recollect a result not fitting into their world view than believers. But I do not want to digress into another field.

And then, of course, we should not forget that pretending misunderstanding someone else can be used as a weapon in a discussion as the following example from a Mudcat thread about Venezuela shows:

President Chavez has been democratically elected (Escamillo)

Unlike one person further North. (McGrath)

further North? Oh I see: Castro! (Wolfgang)
