By doing so, one makes an assumption of the unknown [ 1 ] (for example, a driver may extrapolate road conditions beyond what is currently visible and these extrapolations may be correct or incorrect).
To promote a neutral (useless) product, a company must find or conduct, for example, 40 studies with a confidence level of 95%.

In addition to the main result, Ioannidis lists six corollaries for factors that can influence the reliability of published research. Research findings in a scientific field are less likely to be true, the smaller the studies conducted. the smaller the effect sizes. the greater the number and the lesser the selection of tested relationships.
