Science writer: All scientists have beliefs and values that might slant their interpretations of the data from which they draw their conclusions  However, serious scientific papers are carefully reviewed by many other scientists before publication  These reviewers are likely to notice and object to biases that they do not share
Thus, any slanted interpretations of scientific data will generally have been removed before publication
Biases that are present in published scientific papers and shared by most scientists, including those who review the papers, are unlikely to impair the scientific value of those papers.
