Reseach takes a long time because you have to do it ver and pver again. Sometimes the information that you need ends up thrown away because of human error or some type of that. In one year irreproducible preclinical research cost about $28 billion, and that is only in United States.John A. Pualson school engineering and applied sciences are trying to predict whether experiments can be replicated. Yiling is also trying to find out if your experiments can be replicated but he is doing it with a international team that has been reseaching this for about 3 years. Both John and Yiling have been experiments on crowds. One example of that is how many people are in that crowd they have been doing this for about a year now.
