William perry has done research that shows a transition in the way college students think. they go from a staunch need to have a "right" or "wrong" answer to a more flexible and tolerant way of viewing problems as ambiguous and having multiple levels of "rightness." perry's findings have generally persisted in the decades since they were first published. this demonstrates the principle of

Replicability

Explanation:

In research, we say that a research is replicable when an independent group of researchers can go through the same process that the original researcher went through and arrive at the same results as the original study.

We say that a research is replicable when we can validate someone else's work by trying to reproduce their result using the methods that they have proposed originally.

In this example, William Perry did research that showed a transition in the way college students think. Through time, his findings have persisted in the decades since they were first published, meaning other researchers have come to the same conclusions as he did. Therefore, we can say that this is an example of replicability
