The purpose of this article is to offer arguments in favor of doing broad science, which means focusing on the investigation of everything, supported by the elaboration and application of methods that make it possible to objectify reality, which includes the attempt to replicate evidence likely to come from a transcendent reality. We argue that doing broad science depends on adopting the assumption that there are other dimensions of reality since this broadens the horizon of investigation; and to take care that such assumption does not come to be left out due to the influence of intrusive lines of thought of the most diverse. Here we discuss three lines of thought showing fragility in them, which we understand to be well established in current times, especially in the academic environment, and which directly or indirectly advocate the adoption of a materialist vision, namely: the disconnected psychophysical dualism, the myopic pragmatism, and the primacy of epistemology over ontology.
