the manner in which the audience identifies with the Main Character
The Reach of a story describes the relationship between the audience and the Main Character. An audience might Empathize with a Main Character in which case the audience identifies with the Main Character and sees the story through his eyes. Alternatively, an audience might Sympathize with the Main Character in which case it stands next to the Main Character as if it were a close acquaintance. The story dynamics that determine Empathy or Sympathy are different for men than for women. Women tend to identify and Empathize with a Main Character of either sex who is limited by a Optionlock. Men tend to only Empathize with male Main Characters. Women tend to Sympathize with a Main Character of either sex who is limited by a Timelock. Men tend only to Sympathize with female Main Characters. As a result of these dynamics, sometimes both women and men will Empathize, sometimes women only, sometimes men only, sometimes neither (both will Sympathize). It should be noted that these are tendencies only. Training, experience, and personal choice in any individual audience member can slip the balance wholly to the other side. Nevertheless, at the subconscious level these tendencies will hold true.
