Intelligence is an incredibly complex phenomenon. The greatest minds of the human era have not been able to accurately understand fully and define it. Unfortunately, in today's society it is something that we measure all too frequently. Letter grades for accomplished tasks in school are all too wrong. Sometimes people understand and view things from different perspectives. Not to mention, sometimes people are busy working on other things and cannot dedicate the time. For instance, in high school I worked 40 hours a week. I was a B-C student. My friends, who were not employed frequently got As and Bs. I've worked my way through college and am applying to medical school as a 5th year senior. My friends from high school, who frequently got As and Bs, graduated last year and are living with their parents. I don't think we should measure intelligence. Sure being smart has its benefits, but I'd rather have a hard work ethic and average intelligence than being a lazy genius any day. So in a few years when I have a medical degree and I stand amongst my friends, who do you think is going to be labelled "smarter?"
Here's a question: You must choose one of three doors. Door A has serial killers behind it. Door B is filled with flames and smoke. Door C is filled with lions who haven't eaten in a year. Which door do you choose?

The lion door because they are all dead!

IQ measures intelligence but it is widely agreed that standardized tests can't measure all forms for intelligence including creativity, wisdom, practical sense and social sensitivity.
