What factors lead people to trust and engage with a science blog? One 2014 study found cues for blog credibility include a blogger's self-reported expertise, or the expertise/profession they indicate on their "About the Blog" pages or in their sidebar biographies, for example. Other cues for credibility reported in the study include gender (with readers perceiving female blog authors to be more credible in this case) and community ratings (e.g. upvotes on the blog post).
Interested in more research on science blog readers, or who reads science blogs and why they do? As part of my postdoctoral research, I'm conducting a large-scale survey of science blog readers. Check it out - you can help too!
