"When people don't have access to firearms and get it into their head that they don't think pills are going to work, they think there is something about the finality of [jumping] and think 'If I just do this it will be over,'" said Kaplin, who told ABCNEWS.com that while men and women are equally likely to attempt suicide by jumping, women are less likely to die after the fall because of their lighter body weight. [Emphasis mine.]
It's interesting and unusual to see a non-psychological reason posited to explain the difference between the success rates of men and women who attempt suicide. According to this story, suicide by jumping from heights accounts for only a small proportion of total suicides. But the high (perceived and actual) lethality of the method, coupled with similar rates of attempt and a plausible physical explanation for differential lethality, must make us a bit more skeptical about psychological explanations for the difference in gender rates of suicide success. I feel this lends some support to my hypothesis that women may attempt suicide more, but succeed less, because they have less access to and familiarity with guns.
And, later in the story, "clinical psychologist and suicide expert" Madelyn Gould challenges the idea that suicide contagion affects people who aren't really suicidal:
"[44-year-old New York attending physician Douglas Meyer, who committed suicide by jumping from heights shortly after Korshunova] could think that the model definitely accomplished what she was trying to accomplish and then that method could be seen as an option for him, even if he hadn't readily thought about it before," said Gould, who said this sort of copycat syndrome isn't seen in people who are not already severely depressed or contemplating suicide, and usually only affects those who have already mapped out a plan for their death. [Emphasis mine.]
Of course, this sort of statement, backed up by precisely no evidence, should be taken with a grain of salt, but it's interesting and rare to see any sort of statement challenging the idea that suicide contagion causes people to kill themselves who are not already inclined to do so.
