Brigham Young University researchers have found that 90% of people disregard important security messages if they come up at the wrong time.
The study was carried out by BYU researchers in collaboration with Google Chrome engineers. They found that warning messages appearing haphazardly results in up to 90% of users ignoring them. They found that this is as a result of the nature of the human brain which cannot handle multitasking well even when the tasks involved are simple ones.
The best times to present security messages to users are after watching a video, while waiting for a page to load or after interacting with a website as found by the research.
This research has convinced Google chrome security engineers to change the timing of security messages in future versions of the Chrome Cleanup Tool and hopefully other developers will follow too.
