Second, in studies showing a statistically significant advantage for firstborns, birth order accounts for only one percent of the variance in IQ scores (Sulloway, p. 473). Third, the firstborn advantage is tiny-about 1 IQ point higher than the second sibling, 2 points higher than the third sibling, and so on.Is your IQ set from birth?
Although IQ can change for an individual, across a population it is well established that IQ is stable across the lifespan. This does NOT mean that our abilities do not change as we age.

A two-way analysis of variance indicated that first borns were more introverted than either middle-horns or last-horns, with no difference between the latter two groups. It was suggested that inconsistent results in this area may be due to the use of different measures of introversion.Which sibling is the smartest?
