It's a shame authors like this don't think to delve into the "other" category, because that's where surprising insights can sometimes be buried. For example, I would really like to know the "other" reasons for providing false answers to security questions. The top reasons are obvious, and a couple of them are my reasons. For privacy, and better security, I would put, say, B7eoaOHv2se as my father's middle name, and store it in a password manager. My guess is that "other" breaks out into: - I have one or more of the above reasons but I don't want to reveal it/them. - I don't have one of the above reasons but I don't want to reveal my reasons. - I am lazy. - I like to troll security questions even though I am just trolling a script program on the internet. - I am trolling your survey. - I use it as a chance to express my creativity. - I have never encountered such a question. - I forget how I answered and why. These may overlap. But it would be interesting to see if there are other sensible reasons.
