Context affects opinion about novel energy sources

13.07.2007
Opinions people have about innovations are influenced by the context in which they form their opinion. For example, opinions about a novel energy source like biomass are influenced by thoughts regarding other energy sources. The less knowledge, interest or time people have, the stronger this effect. Sustainable energy options must therefore be promoted in the right context says Dutch researcher Wouter van den Hoogen.

People frequently form opinions about new technologies, such as novel energy options, despite having a very limited knowledge of the subject concerned. The subject is often complex and people are either not particularly interested or have limited time. Wouter van den Hoogen’s research indicates that the opinions people form about various energy sources are related to each other. The researcher argues that an integrated communication strategy should be used for the acceptance of each type of sustainable energy source introduced to the Dutch market. Promoting one specific energy source can adversely affect the acceptance of other new energy sources.

In seven experiments Van den Hoogen examined the boundary conditions within which so-called 'context effects' can occur. A context effect occurs if a person’s opinion about new technologies depends on subtle differences in the context in which the technology is introduced. The theme of these experiments was energy from biomass. It appeared that people were only sensitive for subtle differences in context if they had a weak basic attitude towards the subject. When people had a weak opinion, and another energy source was casually mentioned just before the assessment of biomass, then their opinion about the use of biomass was assimilated to the use of the other energy source. Biomass was assessed more positively if sunlight was mentioned in this context, compared to when coal was mentioned. This is because people use the information in context, as an interpretation framework for assessing the unknown item. Still, this assimilation effect did not always occur in the experiments. Sometimes a comparison with the context led to a contrast effect: in this case, biomass was valued more highly if it was compared to coal and valued less if compared to solar energy. Although the assimilation effects also occurred when people were hindered from thinking, contrast effects required mental effort.

The doctoral research is part of the programme 'Biomass as a sustainable energy source: environmental load, cost-effectiveness and public acceptance' financed by the NWO/SenterNovem Stimulation programme Energy research. The aim of the programme is to develop knowledge in the natural sciences and humanities for the transition to sustainable energy supplies.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
