Why do people ignore security warnings when browsing the web?

We often click and dismiss the warnings our computers give us, rather than acting on them. Worryingly, the reasons may be hardwired into our brains

We may rely on computers, but we don't notice what they're telling us about online threats. Google recently had to redesign the security warnings in its Chrome web browser because most people were ignoring them. What's even more worrying is that our brains may be hardwired to do so.

Like most browsers, when Chrome visits a web site it checks the site's online proof of identity, called an SSL certificate. This certificate come from a third party authority, which performs a background check on the site before issuing it.
