How does Hewish's skepticism apply to the search for extraterrestrial intelligence (SETI)?
My skepticism regarding SETI stems from a fundamental principle: the burden of proof lies with the extraordinary claim. We must be careful not to confuse correlation with causation, nor to overinterpret signals without robust, repeatable evidence. While the search for extraterrestrial intelligence is a fascinating concept, much of the effort has been based on theoretical possibilities rather than concrete, verifiable observations. Until a signal is clearly and unequivocally detected, confirmed by multiple independent observatories, and analyzed to rule out all plausible terrestrial or natural astrophysical explanations, I remain cautious. Science progresses by falsification and rigorous testing, and the claims made in SETI often lack this level of empirical grounding.
