Found an error in an old, protected answer. How to suggest an edit?

Question

Related to this question, but refering to a specific post.

I have 6 reputation so far, but would like to leave some sort of remark (comment, another answer) at an old, accepted answer. How can I do this? This answer might wrongly influence opinions of people searching for the topic, because it seemingly provides more evidence than there is (one supporting study vs. two supporting studies).

While overall, the answer is not neccessarily bad, the way its second reference is quoted is definitely misleading.

So far (when having no reputation), I posted a new question to address this.

And should I move my question to meta? I'm not sure it fits here, either.

"An Examination of Date Rape, Victim Dress, and Perceiver Variables Within the Context of Attribution Theory"

Workman JE, Freeburg EW., Sex Roles, Volume 41, Numbers 3-4, 261-277 (1995)

This study found in part that the way a woman choose to dress is 
sometimes taken as a statement about her character including
vulnerability, desire and/or willingness to have sex and provocation
of males **which consequently affects the likelihood of rape**,
including date rape.

Looking at the paper, this study investigated only the perception of responsibility by people who 'read a date rape scenario' and saw a photo. It does not in any way study the connection between clothing and incidence of rape.

Answer 1

If you don't have enough reputation to take certain actions, but have a concern about a question, you can do one of the following:

• Work to improve your reputation
• Ask a question like this in meta (including the original detail would be helpful)
• Mention it in the skeptics.SE chat room and see if others agree (although our chat room is notoriously underused, compared to some other SE sites)

Regarding your specific concern, there is already a highly upvoted comment by Tacroy making the same point you do about the second study. I've added my own upvote.

The fundamental problem here is that it is hard to imagine a study (at least an ethical one) that could definitively answer the question, as asked.

What are you going to do, dress women differently and send them out into clubs to see which ones get raped? Survey rapists and see who their favorite victims are?

So it might be that studying the way that people perceive women in the scenarios presented in the study might be the best we can do.

Personally, I think most of the answers are looking at this all wrong anyway, the answer to "can you avoid sexual assault by dressing less provocatively" is clearly no, because women of all kinds, in all manner of dress are sexually assaulted on a regular basis.
