The only important discussion to have is "how can we improve our scientific method." Complaining about deficiencies without offering improvements is not particularly useful. There is no alternative to science.

The posters here that are suggesting that people should not trust science ought to be shunned. It is good to be skeptical of particular studies, but if you discard "science" you are reverting to a position of complete ignorance. Always remember that without an alternative model, if you discard a body of research the only valid fallback is that you don't know anything.
