There's an unspoken pact scientists make with the public. In the same way that doctors and police are held by law and by honour to tell the truth and protect, a scientist is entrusted with performing research with integrity and transparency. The research is carried out, the process painstakingly recorded in laboratory books. The results are scrutinised by peers, often repeatedly, until the work is published in a journal, where readers trust that the work is done accurately and without disguise.
Publications are the key to science: they are a public acknowledgement and record of what has been done and how it can be repeated by other scientists. This ability to replicate is the key to truth and integrity: if the results can be replicated, they are valid. A new fact, a new discovery, has been made.
