Human perception assesses risk differently to other threat measures in place
For example, it was shown that individuals value highly their physical health, but usually not their mental health; they are concerned about their lives, but not that much about their lifestyles (Short, 1984). The public worries about "one in a million cancer risk from toxic chemicals, when there are obviously far more dangerous things to be worried about" (Clarke & Short, 1993, p. 380). It can also be said that people who are most concerned about (terrorist) attacks from abroad, tend to be less worried about pollution at home.
