This brought to mind Mendel's experiments on inherited traits, which I don't believe anyone has been successful at reproducing as they were stated. It's unknown whether he got extremely lucky with his pea experiments or fudged the data, but he should not have had a large enough sample to provide the kinds of results he used to extract his laws of inheritance. This was during a different era in scientific research that did not demand nearly the kind of rigor we see today, yet somehow we still got along. The more egregious kind of dishonesty is something like the Bell Curve, where a single exceptional example from a study (one out of 21 if memory serves) was used to essentially propose that minority racial groups were genetically inferior.
