Scientists have long agreed that we humans are a complex combination of our inherited traits and the environments in which we are raised. How the scales tip in one direction or the other, however, is still the subject of much debate. To better understand the nature versus nurture question, UC Santa Barbara psychologist John Protzko analyzed an existing study to determine whether and how environmental interventions impacted the intelligence levels of low birth weight children. The key finding: Interventions did raise intelligence levels, but not permanently. When the interventions ended, their effects diminished over time in what psychologists describe as "the fadeout effect." https://www.sciencedaily.com/releases/2016/03/160314151645.htm
