Is this statistics question appropriate for a survey or is it flawed in someway

in a 1995 corporation for public broadcasting poll of tv ownership, one question was, " A recent study by a psychology professor at a leading university concluded that the amount of violence children see on television has an effect on their likelihood of being aggressive and committing a crimes. From what you have seen or heard about this subject, do you agree strongly with that conclusion, agree somewhat, or disagree strongly?"
is this question appropriate or is it flawed in some way?

Correlation does not imply causation.
X ... "has the effect" is an irresponsible statement.
