VIEWPOINT

Evolution of scientific knowledge

  • Ignore departures from the existing framework of beliefs.
  • Deny that an anomaly exists; blame it on faulty observation or testing error; deride the proponents of the new viewpoint.
  • Acknowledge the anomaly, but call it "idiopathic."
  • Try to explain the anomaly with the existing framework, sometimes by making minor adjustments.
  • Seek alternative viewpoints to contradict or minimize the one proposed.
  • Recognize the new viewpoint as valid, but within a narrow context relegated to "exceptions."
  • Accept the new viewpoint as offering some explanatory power, but retain the old viewpoint, too.
  • Discredit the old viewpoint; deride any attempt to reinstate or rehabilitate it.
  • Accept the new viewpoint with enthusiasm.
  • Begin again.
