People with an internal locus of control believe that they are mostly responsible for what happens to them. Those with an internal locus of control are more self-confident, achievement oriented, more intelligent and so have less of a need for social approval; this means that they will only trust their own beliefs and decisions and so will resist social pressures from others. Also they take personal responsibility for their actions and experiences, so are more likely to base their decisions on their own beliefs, meaning that they resist pressures from others.
