Reading (today)Cortina & Dunlap On the logic and purpose of significance testing
The authors do consider *intriguing" the Cohen´s Modus Tollens example: ____Permise 1: If a person is an American, then that person is probably not a member of Congress ____Permise 2 : The member is a member of Congress, therefore: The person is probably not an American After some degree of hesitation the Authors were lead to conclude that Modus Tollens cannot be invoked if, without exception, must be an American citizen.
What is for me absolutely amazing is the tentative to use Classic Logic in Probabilistic matters . . .
