Pew Research recently asked adults in the US some basic digital knowledge questions as a part of a research study. Out of 10 questions asked, only 20% scored 70% or higher with correct answers. There are some concerns about the questions Pew used though. While the survey asks some good questions, one of the questions doesn’t relate to digital knowledge. It asks to identify a picture of Jack Dorsey, the CEO of Twitter. In another question, Pew themselves got the answer flat wrong. The question “What does it mean when a website has ‘https://’ at the beginning of its URL, as opposed to ‘http://’ without the ‘s’? ” They say, accessing the website means you send and receive only encrypted traffic. This isn’t technically true. In a website with mixed content, where encrypted and nonencrypted traffic passes to the website the URL contains https:// but some areas of the site send and receive unencrypted traffic. Luckily most browsers warn you with a notification in the address bar if you look for it. See this example for a https URL where you send unencrypted content. https://www.bennish.net/mixed-content.html.
