I don't know. I see far too many statistical analyses of various groups of people, and I just don't see the use of them in the vast majority of cases.

Does it take a study to know that people born since the advent of the personal computer are more likely to have had more exposure to technology and to thus be potentially more comfortable with it? Of course not. Do I know a huge number of people of all living generations who have a non-generationally-dependent spectrum of skill and interest in the subject? Of course. I know septuagenarians who are technically proficient and I know teens who aren't, and vice versa.

I tend to shrug at this kind of stuff and just keep in mind that over 90% of convicted murderers in the US were fed mashed potatoes as children.
