(All of the following applies to me, too.) Whether it is vaccination safety, the Middle East, mortgage issues, GMOs, horoscopes, Bigfoot, climate change, space exploration, complex financial situations, legal issues or anything which requires expertise, people need to step back and consider their own ignorance before rushing to judgment or conclusions. Our ignorance is often so glaring that we don’t even recognize it. While you must always think for yourself, you also should listen to all objective information.
There’s nothing worse than a know-it-all who knows very little, but is certain of everything.
Whatever you do, don’t try to correct someone suffering from the illusion of knowledge.
