The achievement of scientific research results and their social recognition often represent huge empirical benefits or even the lifetime achievements of scientists, which makes it difficult to guarantee that scientists will not relax the requirements of scientific principles Violation of regulations; the socialization of scientific research results is often linked to the interests of enterprises, and companies will inevitably conceal hazards when they seek profits; due to the unknown factors of scientific research and the difficulty and time span of dangerous discovery, even scientists and enterprises uphold moral principles, It is also difficult to guarantee that the potential harm of scientific research results can be found. What does this passage mean? ['Application of scientific results should be cautious.', 'The potential dangers of the application of scientific research results cannot be predicted.', 'The economic benefits attached to science corrupt the spirit of science.', 'Moral principles are the primary principles for scientific research.']
