Report Is University Worth The Money? in House prices and the economy Posted August 18, 2011 Just to make some sweeping generalisations: More intelligent people tend to go to university than dumber people. Surely what's needed is a study of people who _could_ have gone to university, but didn't, rather than just looking at averages earnings of each? Even if not "more intelligent", one might consider "more self-confident" or "more ambitious". So you're right that the figures are deeply flawed. On the other hand, short of randomising a group to "uni" and "non-uni" it's hard to see how you can adjust for the self-selection bias.
