Is Missy just as smart as Sheldon?


Missy and Sheldon are twins and people often wonder if she shares Sheldon’s intellect. The answer is technically no, Missy is not smart like Sheldon.


However, the answer is not that simple. Sheldon is intellectually gifted, and book smart, but he lacks social awareness, Missy on the other hand, has emotional intelligence and street smarts and understands people way better than Sheldon ever could.


While Sheldon is great at solving academic problems, Missy is a genius at connecting with people and understanding and solving their problems, which is something Sheldon never managed to achieve.
