Frank R. Stockton said of this story, “If you decide which it was—the lady or the tiger—you find out what kind of person you are yourself.” He pretended that he himself did not know, that although he had planned a decided ending, he could not write one, “for I had not the advantage of being either semi-barbaric or a woman.” Thus, interpretation of this story relies on each reader’s decision, depending on how the reader views the world and human nature in it. The amount of faith the reader has in love and how much the reader believes that jealousy, hate, and pride may alter one’s love will affect that decision. What the reader imagines “semi-barbarism” (that of the princess) to be, as well as its opposite, will also affect his or her own interpretation of the ending.
However, certain points about the story are not open to interpretation. The princess does take the trouble, great trouble, to find out which door is hiding what. She is not her father’s daughter; she does not leave things to chance, for her heart is engaged. She does not hesitate to give direction, nor does her lover hesitate to rely on her. If he trusts her so, would she trust him less? Still, this is a fairy tale, with a fairy-tale way of presentation. Are such complexities of motivation that would lead the princess to indicate the door to the tiger right for such a tale? One may answer no, yet the course of true love is here pointedly crowned with hate and jealousy. A possible theme of “The Lady or the Tiger?” is the necessity of trust in another person’s humanity and love in a world where one never knows for certain what that person will do. The reader may wonder: “Which door would I have chosen?”
