It is important to understand how science works if you are to fully appreciate the strengths and weaknesses of the scientific method. The reason why science is such an effective means of approaching true understanding of the universe around us and our place in it is because scientific theories are always open to revision in the light of new evidence.
Science is therefore self-correcting, and no theory or hypothesis should ever be even tentatively accepted without being subjected to proper critical evaluation. Peer review is the primary means for achieving such evaluation but, as my article shows, the current system does not always work perfectly.
