Via Tyler Cowen, this comes from a Microsoft Research paper about why ordinary people are probably justified in ignoring most security advice on the internet:

Browser vendors have invested considerable effort in making it harder to ignore certificate errors. In Firefox version 3, when encountering an expired, invalid or self-signed certificate the user sees an interrupt page explaining that the SSL connection failed. If he chooses to add an exception he sees another interrupt page with more warnings and a choice to add an exception or “get me out of here.” If he elects (again) to add an exception he must click to get the certificate, view the certificate, and then add the exception. Internet Explorer 8 is somewhat less intrusive, but the procedure also seems designed to suggest that adding exceptions is very risky. Is it? Ironically, one place a user will almost certainly never see a certificate error is on a phishing or malware hosting site. That is, using certificates is almost unknown among the reported phishing sites in PhishTank. The rare cases that employ certificates use valid ones. The same is true of sites that host malicious content. Attackers wisely calculate that it is far better to go without a certificate than risk the warning. In fact, as far as we can determine, there is no evidence of a single user being saved from harm by a certificate error, anywhere, ever.

I’ve long wondered about those certificate errors I get from time to time, but apparently they’re just that: errors. Now I know I can just ignore them and still sleep soundly at night.

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
