One of the problems with the Wahl-O-Mat is you are given 38 questions and big Agree/Disagree buttons, so most people just go with their gut-feeling and click through as fast as possible.

E.g. the question "All of the labour force must be covered by the state pension" sounds great but glosses over the whole problem of provisioning that money for future generations (Germany's worker/pensioner ratio is supposed to sink to 1.7 in 2050) and certainly doesn't cover potential alternatives like an Australian Superannutation style system.
