So if you're physically beaten up, then go into a debate, your wounds would possibly affect your ability to argue, but losing would "take you out" socially rather than physically. Likewise, if you're hella stressed, a wound could "take you out" physically as you're too freaked to compensate.
Damage will probably be in degrees of stress/wound linked to degrees of success. A degree of success will probably be something like every +3 or +4 over target number. Need to sit down with some dice and a friend with a good mind to determine that for sure.
