The philosophical assumption that objective scientific research can uncover true cause-and-effect relationships in the world is known as:

Positivism.

Explanation:

Positivism is a philosophical current that arose in France in the early nineteenth century. She defends the idea that scientific knowledge would be the only form of true knowledge. From this knowledge, one can explain practical things such as the laws of physics, social relations and ethics.

The positivist current promotes the cult of science, the human world, and materialism at the expense of metaphysics and the spiritual world.
