Forgive me but there is some contradiction in your answer. You start with ''An supernatural effect that actually compels you to do something will do exactly that.'' and end with '''ve also found that it's more interesting for all of us to see how the players will handle a situation rather than to tell them how their own characters are behaving.''

I will go with the 'you do what the power says'. Thanks anyway.

I think he means that the effect affects the character, but it's up to the player to describe and portray it. Thus, the use of the power is fulfilled, and the player plays their character. Does that help clarify?

I guess, thank You :-)

I'm saying there is a difference between a supernatural power that actually compels someone to do something and a social skill which influences their general attitudes. Sorry if that wasn't clear.

Indeed, and sometimes the PC's need to play along because a character who isn't phased by anything is boring.
