  Any bi-conditional proposal can be analyzed into a conjunction of two component simple conditionals, both of which must be true if the bi-conditional itself is true. However, only one of the two conditionals will have its antecedent satisfied (depending on what Q chooses to do), and will thus govern what comes about as a consequence.  If the proposal is to have a motivational effect on its recipient, it will be because the recipient prefers that one of the two possible consequents be realized — either that P brings about C, or that P does not bring about C — so we may suppose that it is the difference in Q's valuation of these consequents that motivates (if anything does) Q to act in response to P's proposal. (If the agent is indifferent between the two states, we may consider the proposal to be an offer, but too unattractive an offer to tempt one to accept it.) So we look to the conditional containing the less-preferred consequent, and compare it to the baseline in order to see whether P's proposal makes Q worse off than she would be in the relevant alternative state of affairs. (The following analysis slightly modifies the analysis in Gorr 1986, 391–397; and Berman 2002,   55–59.[9])
