However, the reasoning behind the studies on which these researchers rely is circular, and based on assumptions now known to be unreliable. For example, in some studies, the researchers decided arbitrarily that falls of less than one meter could not harm a baby, so that parents who described such a fall must be lying.
但是，这些研究者的研究所基于的逻辑是套套逻辑，其基础假设现已知道是不可靠的。比如，在一些研究中，研究者武断地认定不足一米高度跌落不会伤害婴儿，因此描述此类跌落情形的父母一定在撒谎。其他研究认为，父母对发现无力辩解便是虐待的证据。
