“Chaos in the brickyard” refers to a letter that appeared in Science in 1963, in which Bernard K. Forscher described scientific research as the building of brick edifices:
“Once upon a time, among the activities and occupations of man there was an activity called scientific research and the performers of this activity were called scientists. In reality however, these men were builders who constructed edifices, called explanations or laws, by assembling bricks, called facts…If the bricks were faulty or if they were assembled badly, the edifice would crumble…”
When investigators from basic and clinical fields collaborate to do translational research, special problems arise in determining whether research results are 'strong'. Examples of current problems will be discussed, along with 'rules of evidence' and broader principles that may help improve translational research.
