We at the<em> International Congress of Infant Studies</em>, <em>the Cognitive Development Society</em> and the <em>International Society for Developmental Psychobiology</em>  hold that the pursuit of knowledge embodied by science is best served by engagement and interaction with all serious scholars regardless of national origin or creed. We are dismayed by any attempt to restrict opportunities for scientists to fully participate in global academic dialogue. Such efforts are immoral and they undermine the scientific enterprise. Understanding the complexity of human behavior requires us to explain how behavior varies across and within cultures.  Policy decisions aimed at helping all children thrive must therefore be based on science that is global and generalizable. We are committed to ensuring participation for scientists of all nations.
