fixed...
now on 10+ they believe in your ideas
this should fix the doubt
as per the "charisma" part... it means that they might or might not believe in your ideas (probably not) but they follow you nonetheless because of the strength of your personality aura... your charisma... in you...
So while with 10+ you changed their moral compass and inner beliefs, with 7-9 you just persuaded/charmed them. They might do the right thing because you ask them to, but not because the believe/understand that this is right.
