Knowledge increases power

This article from Physorg reports on research about the effects of hypothetical questions. Juries often hear hypothetical questions before they are selected, and Sarah Moore, University of Alberta Business researcher, found that these questions can plant a bias. Jurors told ahead of time that they might hear such questions and not to let them influence opinions are far less likely to absorb the intended bias.

Thomas Hobbes said "scientia potentia est" = Knowledge is power. The more you know, the more likely you can develop your own opinion rather than adopting an opinion someone else would like you to have.
