Do we know studies saying that PGP fingerprints are effective?</blockquote><div><br></div><div>Here's a usability study showing that "fingerprints" are both confusing and scary to normal humans:</div><div><br>

There were several participants who immediately associated “fingerprint” with a negative connotation (i.e., leaving a fingerprint at a crime scene). Their tone was panicked in asking their questions on this issue, and were unsure of why that information needed to be displayed, and if it was even safe to display. There were a handful of users who understood encryption technology at a very basic level who were not confused by the terminology on this page, but were unsure of what to do with this information.</span><br>
