The Maybelline makeup brand has been making millions with their moto of "Maybe she's born with it. Maybe it's Maybelline." In reality wearing the Maybelline brand of makeup will not make you any more beautiful. It will only enhance or play up the features you already have. The principle of critical thinking that applies with this is correlation isn't causation. Just because two variables (Maybelline makeup and looking beautiful) are correlated, does not mean that one causes the other. Many people believe in the correlation-causation fallacy that because one thing (Maybelline makeup) is associated with another (beauty), it must cause it. But in reality that is wrong. You can wear no makeup at all and still look good. Nor is it proven that wearing Maybelline makeup makes you any more beautiful.
