Q

Core beliefs of scientific approach

A
  • Empiricism: knowledge is derived from real world observation, not theoretical deduction
  • Determinism: everything has a cause that we can find
  • Objectivity: science should accurately represent reality
  • Replication: science is cumulative, so we need to repeat research to make sure it’s correct
