Loadings from a principal components analysis over seven rating scales averaged across individuals (VARIMAX rotated solution).

* Items are reverse coded to facilitate comparison.Notes: Loadings exceeding 0.4 are in boldface.For each novelty question, the following Likert scale was used: 1 – Strongly Disagree, 2 – Disagree, 3 – Agree, 4 – Strongly Agree.1Nano-scale materials promise benefits for society that are not possible with bulk (non nano-scale) materials.2Nano-scale materials possess novel properties that are not expressed in their corresponding bulk forms.3The novel properties of nano-scale materials cannot be anticipated by knowing the properties of the same material in its bulk form.4Nano-scale materials pose risks for society that are not present with bulk (non nano-scale) materials.5The health and environmental risks from nano-scale materials are not well known to scientists.6The existing methods for assessing health and environmental risks from bulk materials are not suitable for determining risks from nano-scale materials.7There is more uncertainty about the risks from nano-scale materials than the risks from bulk forms.Loadings from a principal components analysis over seven rating scales averaged across individuals (VARIMAX rotated solution).
