I think if people studied the Bible more they would not be so stupid.

Ignorant would probably be a better word.  Ignorant means lack of knowledge, as in:

 

 Hosea 4:5-6
 5.  You stumble day and night, and the prophets stumble with you. So I will destroy your mother--
 6.  my people are destroyed from lack of knowledge. "Because you have rejected knowledge,

      I also reject you as my priests; because you have ignored the law of your God,

      I also will ignore your children.
