Very interesting, but none of this actually comes as a shock. The internet has given me first hand experience of how people process information. In most cases, it is really quite scary.
I think the only solution is to make everyone study science. The scientific discipline actually teaches an awful lot about how to process information. It doesn't of course cover everything, but it gives one a sound logical basis and should help people to extrapolate less quantitive concepts in a more qualitive way.
