I think the main problem is the press goes to psychologists for these surveys, which are as about as scientific as looking up and seeing a star, and assuming they're all little twinkling lights that are only visible at night.
GET REAL! Psychology is studied by Arts students, for god's sake!
After all, the "Einstein" of Psychology is Freud - whose contribution to science is that we all want to kill our dads, f*ck our mums, and if we're scared of spiders it means we're scared of vaginas... what does that tell you about Psychology?
Your understanding of the field of Psychology is a bit outdated, friend. Freud's theories, particularly the ones you mentioned, have been refuted and are not believed by modern Research psychologists. Clinical Therapists do things that have little to no basis in science, but that's a different issue.

Where the media really falls down with respect to science is their understanding of experiment vs. proof.
A theory isn't proved until it has been tested numerous times in various ways and the research has been reviewed thoroughly, to the point where the vast majority of the community can agree on it.
While not impossible, it is extremely difficult to "prove" anything using these sorts of experiments
ReverseEngineered has the right idea, psychological studies strip away a great many complexities in an attempt to reasonably control an experiment. In practice, none of them are capable of
proving a claim about human nature. At absolute best, a psychological "truth" is along the lines of "X is usually the case for the majority of humans". For example: "Humans have two hands, and five fingers on each hand". If you read virtually any peer-reviewed, published, scientific article you won't find any sentences saying "we have proven that doing X causes Y". Not even in physics or chemistry. Well, maybe mathematics.
My point is this: one might, for example, be able to provide
evidence for the claim that "video games increase violent behaviors", but there are always a boatload of caveats, because "video games" and "violent behaviors" are huge categories. What a psychologist can say at the end of a study is something like this (fictitious):
"In our Sample(1), 15 year old boys(2) filled out a survey that contained a series of difficult social situations(3). Half of them played Manhunt(4) for 8 hours before taking the survey, the other half did not. The responses to the social situations for those who played Manhunt were, on average(5), more violent than those who did not play Manhunt."
1) You can never sample everyone, a sample may be biased (see 5)
2) This may or may not hold true for 10 year old boys, or 20 year old boys, or 15 year old girls, we don't know.
3) These may be modeled after real situations, but they're always stripped down and simplified.
4) So we know Something about this one game. What about other games? We don't know.
5) This is also very important. Statistically, all "more" or "less" or "different" means is that it is
unlikely to have happened by chance. Usually Psychology uses a 95% confidence interval, meaning that even if you did everything else perfectly, you'll get the wrong answer 5% of the time.
The way that scientists come to regard something as "proven" or "true" is if, over time, a number of studies by different people find similar results. Personally, I don't believe video games cause violence. Do violent kids seek out violent video games because they find them enjoyable, and provide the results people like Douglas Gentile want to hear? Probably.
