The replication crisis affects dyslexia research as much as any other field. This is facilitated by questionable research practices such as p-hacking, HARKING, as well as publication bias. The goal of this project is to quantify the extent of this problem, by meta-analysing one section of dyslexia research, using a method called p-curve or z-curve analysis.
