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.
Depends on the culture, I suppose. I’m a Korean woman and I’ve always been scolded for being too extreme in my expressions of emotions growing up.
