Ideally, the methods we present - applied to new sources of ’big data’ like Google Ngrams - can be used to prepare for changes in public opinion over the generations on matters of global importance.
The impact of climate science research on society is likely to depend on regular fashion cycles in the public's use of specific keywords relating to climate change, according to new research from the University of Bristol in collaboration with Durham University, published today in PLoS ONE. Alexander Bentley and colleagues found that words commonly used by scientists when discussing climate science - such as 'biodiversity', 'global', and 'isotopes' - follow fashion cycles in public usage as the usage of such words by scientists diffuses into use by non-scientists. According to the authors, this effect may contribute to the impact of climate research on societal perceptions. The researchers used Google's 'Ngram' database, which at present scans through over five million books published in seven languages since the 1500s, to represent public discourse (not scientific discourse) concerning climate science. Since the database was only unveiled a couple years ago, this research is among the very first studies of its kind. They found that, while there is a continual output of climate science, there are pronounced fashion waves in public usage of the main keywords associated with this science. These waves vary in length, but the median duration is about a human generation (2-3 decades).
