To be fair, scientists by and large understand the need of replication, and evaluation in general. It's just in certain fields (e.g. psychology) or circumstances with human subjects, it's very expensive or even infeasible to have well controlled repeated experiments.

[Godel_unicode]

If you don't have well controlled, repeatable experiments (a.k.a. the scientific method) are you actually doing science? I think we should come up with another word for these types of one-off studies.

[gumby]

Many fields advance without solid well controlled, repeatable experiments, at least through various stages of development: cosmology, geology, most of medicine, philosophy, science of mind, etc. You don't consider those all "science"?

There's more to science than Bacon.
