James W. Stoutenborough, Assistant Professor at University of Alabama in Huntsville and ISTPP Fellow, along with Arnold Vedlitz, ISTPP Director, have published in Environmental Science & Policy. Based on results from a national public survey conducted as part of funding awarded by NOAA, the authors analyze two measures of knowledge about climate change - perceived knowledge and assessed knowledge. Perceived knowledge is the respondent's self-reported level of knowledge. Assessed knowledge is an objective assessment of the respondent's level of knowledge. Then, using these two types of knowledge, Stoutenborough and Vedlitz evaluate the relationship between knowledge and concern for climate change and test the Knowledge Deficit Model.
