"If an empirical generalization holds, we can predict that we will observe it whenever we test it with an appropriate study design. In other words, if an effect is real, we expect that we will be able to replicate it."
"However, as several critics have indicated the original series of studies were conducted using a small and cognitively elite student sample (i.e., participants were enrolled at an Ivy League university). Such a skewed sample leads to questions about the generalizability of the results"
"Our studies demonstrate that many psychology researchers overestimate the evidence in favor of a theory if one or more results from a set of replication studies are statistically significant, highlighting the need for better statistical education." 🤷♂️
