Unlike other ways of evaluating theories, the scientific method requires thinkers to test their theories. Scientists still use abstract reasoning to come up with hypothetical solutions to problems, but they also test these hypotheses with experiments to make sure their predictions are correct and to help them make new predictions if they are not. This makes the scientific method useful for solving concrete problems, including reducing carbon emissions in cars or finding vaccines for diseases, but not as useful for solving the broader problems of ethics or law.
The scientific method is also unique in being self-correcting. While the principals of logic have not changed over the past thousand years, scientific understanding is always growing. New discoveries often force scientists to alter their previous interpretations of experiments and create new ones based on more recent data. Because of this, the scientific method can continue to produce new and better solutions to both emerging problems and old problems that were not as completely solved as scientists or the public had previously believed.
In a peer review, experts in a field check the validity of their peers' interpretations before publishing them. While researchers in all research fields perform peer review on some level, it has a particular importance in the sciences. This is because science does not just interpret the world through experiments, it uses those interpretations to make predictions about things that will happen in the future. Thus, solutions that are based on those predictions have that much more assurance of being effective, thanks to the emphasis science places on peer review.
According to the scientific method, experiments have to be reproducible in order for scientists to consider them them valid. Solutions to problems produced by the scientific method also need to be reproducible. While individual problems always have their particularities, the scientific method reduces these factors to a basic model that can be applied to similar, but slightly different situations. For example: scientists might perform crash tests on a particular model of mid-sized sedan and use the data from those tests to improve the safety of mid-sized sedans in general, instead of only with the model they tested.
