“Science does not rest on a solid bedrock. Science is not the accumulation of observations. Science is the attempt to solve problems about the world. This demands guesses—conjectures. These conjectures are then subjected to severe testing; those that survive are provisionally accepted; those that fail are rejected.”

Commentary
Popper's 'conjecture and refutation' model: science begins with bold guesses (speculative hypotheses), not passive observation. These conjectures face severe testing; refutation guides progress. This is more creative and dynamic than inductivism (gathering facts first) or deductivism (deriving from first principles).
Popper emphasizes that science is active problem-solving, not passive observation. Scientists propose bold conjectures (Newton's gravity, Darwin's evolution, Einstein's relativity) and test them ruthlessly. Failure is as instructive as success because it eliminates hypotheses. This model of creative conjecture and critical testing has influenced scientific methodology, management theory, and cognitive science.
