But the logic of the CAPTCHA is "if you get this right, then you are human". Makmanalp was suggesting "if you get this wrong, you are not human", which does not follow logically from the CAPTCHA rule.
It is an example of "Denying the antecedent", or the inverse error: http://en.wikipedia.org/wiki/Denying_the_antecedent http://en.wikipedia.org/wiki/Denying_the_antecedent
- makmanalp 16y agoWho is to say that "if you get this right, then you are human" is the valid premise? I'd argue that the correct one is "If you're human, you get CAPTCHAs right". :P
