"And so, you can do hundreds and hundreds of studies showing a general factor and just so long as you restrict your populations, your testing materials and the kinds of situations you look at, you can keep finding the same wrong thing again and again"

This quote by Robert Sternberg is referring to the principle of the basic aspect, which is the concept that intelligence can be measured by a single aspect. Sternberg is recommending that if scientists limit the populations, testing materials, and circumstances they look at, they can keep discovering the exact same wrong thing again and once again. This indicates that the general element is not an accurate measure of intelligence, as it does not take into account the various contexts and situations in which intelligence can be revealed. Sternberg is recommending that intelligence is more intricate than a single aspect, which researchers ought to take into consideration the different contexts and situations in which intelligence can be expressed in order to get a more precise measure of intelligence.
