Nanotechnology in Dutch science cafés: Public risk perceptions contextualised

Area of Science:

• Nanotechnology
• Public Perception
• Science Communication

Background:

• Understanding public attitudes towards nanotechnology is crucial for informed dialogue and participation.
• Science cafés serve as a platform for public engagement with science and technology.

Purpose of the Study:

• To quantitatively analyze risk perceptions and attitudes of Dutch science café participants regarding nanotechnology.
• To compare these perceptions with a general public sample interested in science and technology.
• To qualitatively explore the discussions within science cafés to enrich quantitative findings.

Main Methods:

• Quantitative analysis of risk perceptions and attitudes among 233 Dutch science café participants and 378 non-participants.
• Qualitative analysis of science café meetings to contextualize quantitative data.
• Comparative analysis between science café attendees and a science-interested public sample.

Main Results:

• Both groups exhibited positive attitudes towards nanotechnology, with science café participants being more positive.
• Perceived risk applications of nanotechnology predicted attitudes only for the non-participant group.
• Qualitative data indicated that participants and speakers valued discussing nanotechnology's risks, benefits, and related issues.

Conclusions:

• Science cafés appear to foster more positive public attitudes towards nanotechnology.
• The discussion of risks and benefits is a key component of effective science café interactions.
• Further research should explore the role of science cafés in the broader science-society debate.
