I don't think anyone can deny that everybody lies. So why haven't we figured out how to detect when someone is in fact lying? It shouldn't be so hard right? Well, research has shown otherwise. There are several types of lie detecting techniques, yet none have proven to be trustworthy. In my opinion, lying is something that no one will ever be able to figure out. People are too good at it, which is really quite sad if you think about it.
After some research, I found that lying begins at an incredibly young age. Most children fib by the age of 3. When I read that piece of information, I was shocked, even questioned it. However, after thinking about my little sisters (still very young) it made sense. They both started lying at around that age. It just makes me think that they must have picked it up from the rest of the family, including me.
Obviously we should keep researching the topic, even if we will never figure it out (which is just my guess) we can still learn a lot more about the topic. For example, even though we know that modern lie detector tests are not super effective, we have still learned from them.
