The Fitbit Flex is an activity tracker aimed at measuring your exercise, diet and sleep. The device was my constant companion for about a week, and by the end of it, I felt informed about my activity levels, and was motivated to get moving.
Whether we like it or not, we're constantly judging the intelligence of others, estimating their level of competence by evaluating their responses to our questions. Some people are better at detecting intelligence than others, but that doesn't mean you can't learn how. With practice, you should be able to gauge the intelligence of others with a decent degree of accuracy, though you should always be prepared for surprises.
Actual IQ tests, like the Stanford-Binet Intelligence Scales or the Wechsler Adult Intelligence Scale (WAIS-IV), contain several hundred questions and take, in the case of the WAIS-IV, between 60 and 90 minutes to complete. Then thereâs the way that IQ scores work. IQ points are arranged along a bell curve so that 100 is at the top of the bulge with most of the scores surrounding it. 100 should always be the average score of an IQ test within its intended audience.
