For his most revolutionary discoveries, Darwin recorded his extensive observations in notebooks annotated by speculations and thoughts about those observations. Although Darwin supported the inductive method proposed by Bacon, he was aware that observation without speculation or prior understanding was both ineffective and impossible.

In fact he stated this view clearly by saying, “I could not help making hypotheses about everything I saw.” (Darwin, 1958). The techniques advanced by Darwin have been widely used by scientists such as Goodall and Fossey in their primate studies. Scientific knowledge is gained in a variety of ways including observation, analysis, speculation, library investigation and experimentation.

When preparing school laboratory reports, students are frequently told to present their methods clearly so that others could repeat the investigation. The conclusion that students will likely to draw from this requirement is that professional scientists are also constantly reviewing each other’s experiments to check up on each other. Unfortunately, while such a check and balance system would be useful, the number of findings from one laboratory checked by others is small.

In reality, most scientists are simply too busy and research funds too limited for this type of review. It is interesting to note that when scientific experiments are repeated it is usually because a scientific conclusion attacks the prevailing paradigm. In the recent case of cold fusion, scientists worldwide dropped what they were doing to try to repeat the findings provided by Fleishman and Pons.
In fairness, these two scientists not only assailed the conventional wisdom but presented their results in a press conference rather than in a peer-reviewed journal. Therefore, the community of scientists had two reasons to be suspicious. One can infer a measure of the disdain exhibited by the scientific community toward cold fusion and its “discoverers” in the titles of several new books on the subject.
