There’s a myth that people who are supposedly left-brained are more analytical and those who are right-brained are more creative except that is a complete myth. People that use this theory either do not realise that the science behind the myth is outdated and has been found false or they use it to promote their tests and books which scam people into buying it because most of the tests to see if you’re right or left brained cost money and the people that run these sites are scamming people out of their money. Everyone uses both sides of their brain, we need to use both sides of our brain because we can’t just rely on one side, while the right side is about our creativity, intuition and emotional side, our left side is about our logical thinking, mathematics and numbers which is needed for our everyday life. While some people might use one side more than the other, they might be more analytical than emotional or understand art more than they do mathematics, it doesn’t not mean we don’t use one side of our brain and we need both sides to interpret and understand the world.
