In the Scientific Method we come progressively closer to the truth by revisiting our interpretations as new data accumulate. This means that errors will commonly occur along the way to that “ultimate truth.” Dr. Richard Laub spent several decades excavating a complex paleontological/archaeological site in western New York. The complexity led to mistaken interpretations while, at the same time, the long duration of the project provided opportunities to recognize those mistakes. Laub will discuss some of the erroneous conclusions that peppered his career, and why he feels they were beneficial to him.
