As is the case here:
No matter which category you click on, the distribution across age groups show limited variation, across media. And printed books still lead the reading game.
Now, on other topics, though, generational comparisons might lead to significant differences.
In this case, there is a clear generational pattern that holds over time (and also holds true over other dimensions of religiosity).
In other words, the fact that individuals are born within the same time period cannot be assumed to create homogeneity on a variety of attitudes and behaviors but the fact that Paula Deen and her defenders rushed to that explanation is reflective of how much we tend to assume that a given zeitgeist deterministically shapes an individual’s view, with little to no possibility of change. First of all, to be born during a given time period means something different across borders, and within borders (based on social class, race, and gender).
An assertion of consistency across a generational cohort should always be supported by evidence, and not assumed. It might exist in some respects (like religiosity), but not in others (reading habits).
