Researchers had some control over variables - guards and prisoners had roles only by chance so it was due to pressures of the situation rather than their personalities that they behaved in such a way. Control increases the internal validity.

Major ethical issues - Zimbardo was both lead researcher and superintendent. Issues arose when someone wanted to leave but he had to respond as a superintendent worried about the running of his prison. Limited his ability to protect them from harm.
