This type of research is just BS to begin with. The way they collect and analyze the data is only capable of generating conflicting evidence while never leading to cumulative knowledge. The method is called NHST (null hypothesis significance testing). The main issue is that a null hypothesis is tested rather than any real hypothesis, then they try to draw conclusions about the real hypothesis (yes it is a simple strawman argument). These problems are well known, yet it continues. I was trained to do it not too long ago.
