We used a market research firm to invite participants to take our survey. External
panelists have been used increasingly in IS research (e.g., [4, 13, 51]) and have
certain advantages over traditional methods that were key to our study. First, panels
guarantee respondent anonymity and thereby encourage honest responses to questions
that may be subject to socially desirable responses. Second, external panels contain
respondents from a wide range of industries and positions who would be difficult
to obtain otherwise. This sample heterogeneity reduces potential bias due to unique
organizational factors
