This is a knit-picking based on prescriptive linguistics, but:
“Subjects thought that [...] homicide was a more frequent cause of death than suicide [...]”
Homicide actually means “death of a person” so homicide IS more frequent cause of death than suicide, as suicide is a small subset of homicide, along with manslaughter and murder.
I don’t know where you got that definition from, but it disagrees with common usage and the dictionary. All of the “cides” are about murder, not death (patricide, regicide, suicide, etc), which could have been a clue, since “suicide” would be nonsense if this pattern held.
