Critiques of science often stem from misapprehensions of its iterative nature. Clarifying these can rebuild public trust:
- “Science is always changing, so it cannot be trusted.”
- Rebuttal: Scientific knowledge is cumulative. While theories evolve (e.g., Newtonian physics refined by relativity), they rarely collapse entirely. Plate tectonics, once controversial, now underpins geology because it survived decades of falsification attempts.
- “Scientists disagree, proving that science is unreliable.”
- Rebuttal: Disagreement drives refinement. The 17th-century debate between Newton (light as particles) and Huygens (light as waves) led to quantum theory’s dual understanding. Consensus emerges over time—e.g., 97% of climate scientists agree on human-driven warming.
- “A single flawed study disproves an entire field.”
- Rebuttal: Science relies on convergent evidence. No single paper proves gravity; thousands of experiments and engineering feats do. Wakefield’s debunked autism-vaccine study was an outlier in a field supported by decades of epidemiological data.
- “Peer review is biased and untrustworthy.”
- Rebuttal: While biases exist (e.g., gender or affiliation preferences), reforms are underway. Platforms like PeerJ publish reviewer comments, and initiatives like SAGER guidelines combat gender bias in reporting. Peer review’s value lies not in perfection, but in its capacity to improve.
