People would take more steps to protect themselves. But it needs to be much easier. Websites should have a consistent method for logging in so password managers work 100% of the time. That they work consistently. To help password manager's websites should use a standardized login page, password update page and account creation page. So, password managers can always login and can always know to save a new user/password.
Then the password managers need to keep working the same way all the time. If you have to, fire everyone in involved in the user interface. It should never change. You can change the technologies behind the scenes to make it more secure but the UI should always be the same. All the UI department should do is fix the UI when it breaks due to a change behind the scenes.
We are talking about people where you need to tell them to click on the beach ball (Chrome) not the blue E (Internet Explorer) for safer web browsing. If that beach ball disappears they think it is gone forever. Even if it is still installed they will never get it back.
These are people where you look in the downloads folder. Just about every file has been downloaded ten times. Either they finally realized it was downloaded or just gave up thinking the link was broken.
If you want them to improve security. You must make it easy for them to do so. Otherwise it will never happen. An inconsistent user experience makes a tool unusable. Most people have no grasp of what a computer is doing or how they are interacting with the software. They memorize a procedure. If that procedure changes, they are thrown for a loop. Which is why I stress the need for consistency.
There would have been no resistance to Windows Vista, 7, 8, 10, &c. If MS just stuck with the Windows XP interface. If they just updated all the security and technology behind the scenes but kept the GUI the same. Most people would have been happy.
As for their opinions on encryption. They don't know anything about it. Each of those pole question should also include the response choice of "I don't understand this computer stuff". In which case the answers would be 1% for strong encryption, 0.1% against, 98.9% doesn't understand.
