What do you call a person who believes in science?

 A person who subscribes to and upholds the tenets of science is commonly known as a scientist. Scientists engage in the systematic study of the natural world, employing empirical evidence and rigorous methodologies to form conclusions. Their commitment to objectivity and the scientific method distinguishes them in their pursuit of knowledge.

Belief in science extends beyond the professional realm, with individuals adopting a scientific worldview as a personal philosophy. This perspective values critical thinking, evidence-based reasoning, and a commitment to constantly questioning and refining one's understanding of the world. Embracing the principles of science often involves a recognition of the provisional nature of knowledge, acknowledging that scientific theories are subject to change based on new evidence.

In broader terms, someone who believes in science may be described as having a rational and evidence-oriented mindset. This perspective fosters a curiosity about the natural world and an appreciation for the power of inquiry and experimentation. It is a mindset that not only respects the achievements of scientific inquiry but also actively seeks to apply scientific thinking in various aspects of life.
