We know that poverty does have a negative effect on IQ. The proof is pretty clear. The stresses of poverty consume so much energy that it reduces cognitive function. However, the evidence also demonstrates that IQ can improve in time, and under the right circumstances. Studies also show it’s most likely, though, to improve before adulthood, and that’s why quality education is an absolute must in our fight against, what President Johnson called, “man’s most ancient foe.”
Nevertheless, the old adage must be stressed, it’s never too late to learn.
Take Away: Learning, not necessarily schooling, breaks the chains of poverty.
