 In its place , Stevens suggests that determining whether an intervention is a throffer depends not on the desirability of compliance and noncompliance when compared to the norm , but on the desirability of the actions entailed in compliance or noncompliance when compared with what their desirability would have been were no intervention made . He proposes that a throffer is made if P attempts to encourage Q to do A by increasing " the desirability to Q of Q doing A relative to what it would have been if P made no proposal and decrease the desirability to Q of Q doing not @-@ A relative to what it would have been if P made no proposal " . An offer , by contrast , increases the desirability to Q of Q doing A compared to how it would have been without P 's intervention , leaving the desirability to Q of Q doing not @-@ A as it would have been . A threat decreases the desirability to Q of Q doing not @-@ A compared to what it would have been without P 's intervention , while leaving the desirability to Q of Q doing A as it would have been .
