First, text mining is used to extract statements about the effect of drugs on gene expression in breast cancer. Then two different teams semi-automatically tested these statements using two different protocols, and two different cell lines (MCF7 and MDA-MB-231) using the laboratory automation system Eve."

ONGOING METHODOLOGICAL CRISIS IN SCIENCE STEMMING FROM FAILURE TO REPLICATE MANY STUDIES
Replicability crisis; Replication Crisis; Crisis of science; Science's crisis; Reproducibility crisis; Smart Assays Biotechnologies
The replication crisis (also called the replicability crisis and the reproducibility crisis) is an ongoing methodological crisis in which it has been found that the results of many scientific studies are difficult or impossible to reproduce. Because the reproducibility of empirical results is an essential part of the scientific method, such failures undermine the credibility of theories building on them and potentially call into question substantial parts of scientific knowledge.

Credibility theory

Credibility theory is a branch of actuarial mathematics concerned with determining risk premiums. It is employed to combine multiple estimates into a summary estimate that takes into account information on the accuracy of the initial estimates. For example, in group health insurance an insurer is interested in calculating the risk premium, R P {\displaystyle RP} , (i.e. the theoretical expected claims amount) for a particular employer in the coming year. The insurer will likely have an estimate of historical overall claims experience, x {\displaystyle x} , as well as a more specific estimate for the employer in question, y {\displaystyle y} . Assigning a credibility factor, z {\displaystyle z} , to the overall claims experience (and the reciprocal to employer experience) allows the insurer to get a more accurate estimate of the risk premium in the following manner:

The credibility factor is derived by calculating the maximum likelihood estimate which would minimise the error of estimate. Assuming the variance of x {\displaystyle x} and y {\displaystyle y} are known quantities taking on the values u {\displaystyle u} and v {\displaystyle v} respectively, it can be shown that z {\displaystyle z} should be equal to:

Therefore, the more uncertainty the estimate has, the lower is its credibility.
