JFK was running for president when I arrived here to work on my masters degree in engineering. IDK about his IQ, but he was one of the most charismatic on TV interviews with a wonderful sense of humor during his presidency. I enjoyed watching his frequent news events with the media.
JFK also got a tax-cut passed (for businesses) which helped recover from the recession in 1962.
115 was considered bright and in the top 25% of the population, so great things can come out of that. It seems higher IQ people are being counted more frequently now b/c autistic spectrum people are being included in the count, JMO.
