When narratives speak louder than numbers: the effects of narrative persuasion across the stages of behavioural change to reduce air pollution.

Is narrative persuasion effective when promoting new behaviours in favour of the environment? Does this effectiveness vary depending on whether individuals are already thinking about changing? This paper has two main objectives: (1) to explore how individuals at different stages of the behavioural change process perceive air pollution, focussing on the perceived psychological distance of its environmental risks (Study 1); and (2) to test whether the effects of presenting the risks of air pollution in a narrative vs. statistical format on pro-environmental intentions vary depending on the individuals' stage of behavioural change (Study 2). Study 1 ( = 263) is based on a survey measuring individuals' perceived psychological distance of the environmental risks of air pollution, and the perceived effectiveness of different pro-environmental behaviours.

Consistent or inconsistent? The effects of inducing cognitive dissonance vs. cognitive consonance on the intention to engage in pro-environmental behaviors.

How do individuals rationalize the cognitive dissonance between their environmental awareness and the maintenance of environmentally unfriendly behaviors? The main goal is to explore the rationalization strategies used by individuals in order to maintain their current behaviors. The secondary goal is to understand if it is possible to induce cognitive consonance, and how this influences intention to change. We present a study ( = 222) with three experimental conditions: inconsistency, control, and consistency.

Modernizing confidence-building measures for the Biological Weapons Convention.

The Seventh Review Conference of the Biological Weapons Convention in December 2011 provides an opportunity to modernize the treaty to better address the challenges of the 21st century. The key to this modernization is to redesign the treaty's Confidence-Building Measures (CBMs), the only formal mechanism for increasing transparency and demonstrating compliance with the treaty, to address changes in the global scientific, health, and security environments since the end of the Cold War. The scope of the CBMs should be expanded beyond state-run biological warfare programs to encompass a broader array of threats to global security, such as biological terrorism, laboratory accidents, dual-use research, and disease pandemics.
