对大约四英寸的追赶性增长的来源和意义表示怀疑的批评者声称，奴隶贩子造成的基于市场的扭曲使儿童和青少年的身高测量产生了偏差。在这里，我们使用国家档案馆提供的所有奴隶清单的新数据库来分析这种可能的偏见。采用程序将托运人的姓名与已知或可疑的专业交易员进行匹配，我们发现，由于交易员的选择性而导致的年龄差异相对于四英寸的追赶生长而言可以忽略不计。
Critics who doubt the sources and meaning of some four inches of catch-up growth claim that market-based distortions created by slave traders biased measured heights of children and adolescents. Here we analyze this possible bias using a new database of all slave manifests available at the National Archives. Employing procedures to match names of shippers with known or suspected professional traders, we find that biases in height by age due to trader selectivity were negligible relative to the four inches of catch-up growth.
