I am expert in very, very few things. That said, in those areas where I am expert, my expertise is hard earned through study, work, experience and aptitude. Expertise is fluid, it comes and goes as time passes and without constant study, work, experience and aptitude, it will dilute. No expertise comes from attending the ‘universities’ of Google, Youtube and Wikipedia nor the gossip columns of Facebook or Twitter. But unless you are an expert in exactly the same fields as me, then your opinion is not just as valid as mine. It is not. It cannot be.
You see, ‘Confirmation Bias’ exists. Confirmation Bias is the tendency for you to search for, interpret, favour and recall information in a way that confirms or supports your previous and present beliefs or values. It does exist and only fools believe they are free of it. Your ignorance is not the same as an expert’s experience and expertise.
Genuinely smart people will look for answers from people who are equal or otherwise smarter than themselves. Only ignorant people believe their guess is as good as anyone else’s guess.
