Conventional Wisdom

Hello Lovelies,
I would like to talk to you today about Conventional Wisdom. Conventional Wisdom is defined as "something that is generally believed." (referenced from Dictionary.com) Examples of this are: Blondes have more fun, Name brands are the best, All British persons like tea, etc.
In my class called Issues we are talking about conventional wisdom about gangs and drug dealers. Scandalous I know! You're probably sitting there reading this and wondering how our school system can teach a class about Drug dealers and Gangs, well the class isn't just about that. It's about what people think on certain subjects and how Sumo Wrestlers and a School Teacher are the same? We are reading the book called Freakonomics. It's a great book that's challenges the norms of society.
We have all been victim to conventional wisdom, even if you are sitting there saying oh no I haven't. Well you're wrong! Do you wash your hair everyday because someone told you it was the best thing? Do you get LED lights because they are supposedly the best? That's conventional wisdom.
Conventional Wisdom occurs in everyday life. I want to leave you with this thought. What conventional wisdom do you take part in? How can conventional wisdom hinder or help your daily life?
Comment below what these things are and I'll reply and read all of them.
