what is the iq of sheldon from the big bang theory
Sheldon Cooper Sheldon possesses an eidetic memory and an IQ of 187,[26] although he claims his IQ cannot be accurately measured by normal tests.[27] He originally claimed to have a master's degree and two doctoral degrees, but this list has increased.[28][29] Sheldon has an extensive general knowledge in many subjects including physics, chemistry, biology, astronomy, cosmology, algebra, calculus, economics, computers, vexillology, engineering, history, geography, linguistics, football, trains, Star Trek and in addition to being fluent in Klingon, has some knowledge of Finnish, Hindi and Mandarin.[30] He also shows great talent in music, knowing how to play the piano (as does Parsons in real life), the bongos, the recorder, theremin (which Parsons learned to play in real life), showing some skill in Tuvan throat singing and also having perfect pitch.[31] Although his friends have similar intellects to him, his eccentricities, stubbornness, and lack of empathy often frustrate them. Sheldon occasionally uses slang (in a very unnatural fashion), and follows jokes with his catchphrase "Bazinga!" which is now an officially registered trademark of Warner Bros.[32][33] He is uncomfortable with human physical contact and has germophobia, which makes his exceptionally rare hugs extremely awkward and painful-looking. He also has hemophobia.[34] Sheldon has difficulty coping when asked to keep a secret, when he is interrupted, or when he hears arguing.[35][36][37] He is also a notary public and uses his knowledge in law and contracts usually for his own advantage and is always distressed when challenged in a legal aspect that he cannot logically defend. In his mannerisms, Sheldon also shows symptoms associated with obsessive-compulsive personality disorder. Whenever approaching a person's home, he must knock three times, then say the person's name, and must repeat this at least three times (where "The first one is traditional, but two and three are for people to get their pants on"), as a result of him walking in on his father with another woman when he was thirteen.[38] Upon entering a person's home, he must select the proper seat before sitting down. When it is suggested by Penny that he "just sit anywhere", his response is "Oh, no, if only it were that simple!" This extends to his inability to accept change. His rigidity in maintaining homeostasis often causes him frustration. Because of his rigidity and stubbornness, only his mother and Bernadette[39] – both possessing strong maternal personalities – have shown the ability to order him to do things.
