Its a usability study that explains why PGP is not usable > for common folks. If required I can add a shopping-list of other usability studies looking at why PKI in general is not usable for common folks. There's a summary in the slides at http://www.cs.auckland.ac.nz/~pgut001/pubs/phishing.pdf, and a really long analysis (100-odd pages total, although it covers lots of other areas as well) at http://www.cs.auckland.ac.nz/~pgut001/pubs/man_usability.pdf. (Note that I'm not saying ditch PKI-based auth altogether, keep it if you want, but don't insist on making it a mandatory option in TLS if it doesn't work to protect users).
