He added that he did not consider himself to be a “hired gun” or a professional witness, having participated in just three trials and one arbi-tration in 30 years. He suggested a series of simple principles by which experts could both participate meaningfully in litigation and also main-tain their integrity:
Design and perform the work on your own professional and ethical terms
Publish all results in peer-reviewed journals, irrespective of the outcome
Strive for equal objectivity whether working for the plaintiff or the defendant.

One reason is that cross-examination will tend to expose any weaknesses in methodology or conclusions. Another reason, of more general consequence, is that the effects of litigation may go beyond the finding of facts in specific cases to ultimately influence public policy.
