The two faces of Janus, or the dual mode of public attitudes towards snakes.

Snakes are controversial animals, therefore a better understanding of public attitudes is critical for their effective protection and future survival. The attitudes towards snakes of 951 adults in Greece were investigated in personal interviews. Factor analysis revealed a dual mode of attitudes: respondents were highly intolerant of snakes, while they supported their conservation at the same time. Respondents had high knowledge about the behavior of snakes, medium knowledge of their biology and were strongly affected by folklore. Structural models revealed that tolerance was a positive mediator of conservation. Knowledge about snake behavior and biology was positively correlated with attitudes towards snakes. Moralistic and naturalistic attitudes were positively, and dominionistic attitudes negatively, correlated with snake tolerance and conservation attitudes. Younger, more educated people were more snake-tolerant than older, less educated people. Females were less snake-tolerant and more conservation-oriented than males. These findings increased the understanding of human attitudes towards snakes and helped identify factors critical for their conservation. As such they could be used to design environmental education programs incorporating both information-based and experiential activities that will improve attitudes, behaviors and, eventually, the chances for the survival of these uncharismatic animals.
