I. Scientific Method
A. In the spirit of the true scientist, the examiner/expert will make an adequate examination of the material, applying those techniques and tests essential for proof. He/she will not, merely for the sake of bolstering his/her conclusions utilize unwarranted or superfluous tests in an attempt to give apparent weight to his/her results.
B. The modern scientific mind is an open one, incompatible with secrecy of method and technique. Scientific analyses will not be conducted by "secret processes," nor will conclusions in case work be based upon tests and experiments that will not be revealed to the profession.
C. A proper scientific method demands reliability of validity in the data analyzed. Conclusions will not be drawn from materials which themselves appear unrepresentative, atypical or unreliable.
D. A truly scientific method requires that no generally discredited or unreliable procedure or technique be utilized in the analysis.
E. The progressive worker will keep abreast of the latest developments in scientific forensic, metrology methods and techniques, and in all cases view them with an open and unbiased mind. This is not to say that workers need not be critical of untried or unproved methods, but that workers will recognize superior methods if and when they are introduced.
