I am releasing this public opinion data on behalf of the Extinction Rebellion. It was commissioned from YouGov. YouGov surveyed a sample of 1654 UK (without Northern Ireland) adults between 30th April and 1st May 2020 using an active sampling procedure that approximately balanced the sample to nationally representative quotas for age, gender, social grade, education level, region, political attention, and 2019 General Election and 2016 EU Referendum votes. YouGov further calculated a weight variable using the above variables to match the sample to national population records. In a between-subjects design, participants were instructed to read one of two randomly selected speeches and then respond to three questions in randomised order, with responses on seven-point Likert scales: “Based on this speech, how likely would you be to vote for this politician?”, “Are the values displayed in this speech similar or different to your own values?”, and “Do you agree or disagree that the arguments in this speech make good sense?” The speeches were as follows: Environment unaffordable: “Thanks to the sacrifices of doctors, nurses, other key workers, and everyone doing their bit by staying at home, we may soon have passed the peak of the COVID-19 pandemic. The time will then come to repair the very serious damage to our economy. As we do so, there will be those who call for the environment to be a key focus as the economy is rebuilt. However, we must not be distracted by attempts to link COVID-19 and climate change. Warnings from experts should not be ignored, but these two threats are different and each requires us to act differently. The pandemic has caused so much damage to our economy that we can't currently afford to focus on the environment. Only with a prosperous economy will we later be able to resume our focus on climate change.” Environment prioritised: “Thanks to the sacrifices of doctors, nurses, other key workers, and everyone doing their bit by staying at home, we may soon have passed the peak of the COVID-19 pandemic. The time will then come to repair the very serious damage to our economy. As we do so, there will be those who call for the environment to be a key focus as the economy is rebuilt. And indeed, we must learn the lesson that we ignore warnings from experts at our peril, with regard to pandemics or climate change. COVID-19 is a wake-up call, but one that shows we can act. The environment must therefore be at the heart of our future economy, as we rebuild a society prepared to tackle catastrophic climate change. Only if we also address this threat will a prosperous economy be sustainable.” The released data is in both SPSS format (exactly as provided by YouGov) and in .tsv format directly exported from SPSS. In addition, an SPSS exported code book is provided.
