“Beware of false knowledge; it is more dangerous than ignorance.” – George Bernard Shaw
I’ve talked recently about the idea that a little knowledge can be dangerous. Knowledge is a fragile thing. We can be 100% certain about something, but in truth being totally wrong. Take a look in the past and you’ll see many obvious examples of what I’m saying.
We thought that the earth was flat and we were wrong. Medical history has a great record of how many stupid beliefs we had. Bloodletting was used as a treatment for almost 3000 years. Why did it persist for so long? Because of the social, economic and intellectual pressures.
The medical field isn’t the exception. We most likely believe in the wrong for many aspects of life. It’s hard to make society change an idea. In the 1980s, saturated fat was seen as bad for the health. The idea is still around today even if we have evidence of the opposite.
The problem isn’t just about what we know and don’t change. It is also about what we totally ignore. We might be doing things that could lead to irreversible damage by our ignorance. You should be aware of that blindness and remember that a Sword of Damocles might be above your head as you read those lines.
