A public sample of Hong Kong Chinese (N= 167) rated the levels of threat of 25 environmental hazards and gave quantitative judgments to six risk characteristics for each hazard. It was found that women, older participants, and less educated individuals found the hazards to be more threatening to the environment than did men, younger participants, and more educated individuals, respectively. A new spatial model emerged from a principal component analysis carried out on responses to six risk characteristics. Instead of replicating the well-documented factors of unknown risk versus dread risk, we found a structure defined by a known and dread risk factor and a controllable risk factor. Findings were discussed in light of potential influences of the Confucian heritage on the perception of risks among Hong Kong Chinese.
