An old joke about Albert Einstein illustrate the relationship between IQ and Investing
Einstein passed away and went to heaven, where he was informed that his rooms was not yet ready. He was told by an angel who was responsible for new arrivals: “I hope you will not mind staying for a while in a dormitory. I am sorry, but it is the best we can do right now.” The angel escorted Einstein to meet his roommates, saying, “This is your first roommate. She has an IQ of 180!”
“That’s wonderful!” exclaimed Einstein. “We can discuss mathematics!”
The angel then said, “Here is your second roommate. His IQ is 150!”
“Why, that’s wonderful,” responded Einstein. “We can Discuss physics!”
The angel finally said, “Here is your third roommate. His IQ is 100!”
“That’s Wonderful!” said Einstein. “Where do you think interest, rates are headed?”
The smarter you think you are, the more you get into trouble things like trying to predict things that are not predictable.
Due to overconfidence, a person with a high IQ can actually make more mistakes that someone whose IQ is 30 points lower.
