Abstract
With this experiment we aim to investigate whether the evaluation of policy reforms regarding the German public pension system changes, when participants are confronted with the demographic change in Germany in a control and treatment group setting as part of a survey experiment. Furthermore, the role of understanding about and attitudes towards the pension system is analyzed.

Experimental Design
Experimental Design
The participants are randomly sorted into one of the two treatment groups or into the control group. Treatment group A is asked about its prior beliefs of the number of citizens in retirement age per 100 citizens in working age in the years 2020 and 2050. Then this group is provided with the true information. Treatment group B is also asked about its prior beliefs, but does not receive any information. The control group is not asked about its prior beliefs and is not confronted in other ways with the topic of demographic change.
