Review:
Karl Popper Falsifiability
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Karl Popper's falsifiability is a foundational concept in the philosophy of science that proposes falsifiability as the demarcation criterion between scientific theories and non-scientific ones. According to Popper, for a theory to be considered scientific, it must be testable and refutable through empirical observation or experimentation. This idea emphasizes the importance of making bold, risky predictions that can potentially be proven wrong, thereby ensuring the scientific integrity of hypotheses.
