I think that one of the best examples from the text to show that Tituba is naive is her trusting of Hale and the others once she is accused. Tituba thinks that by naming others, it might help to deflect the attention that is placed on her:
You work for me, Tituba, and I make you free! I give you pretty dress to wear, and put you way highup in the air and you gone fly back to Barbados! And I say, You lie, Devil, you lie! And then he come one stormy night to me, and he say, Look! I have white people belong to me. And I look…And there was Goody Good.
Tituba later implicates Sarah Osburn. She believes that by admitting to the devil's control and naming names, she will be left alone or that she will be able to experience her own feeling of power. This is naive because someone like Tituba will never have power in Salem and the only reason she is sought after now is because she is being used as a means to an end. It is here where Tituba is demonstrating a sense of the naive, a belief that somehow her interests are served by pandering to the interests of the accusing contingent in Salem.
