Science must avoid anecdotal evidence, often termed 'anecdotal science,' where personal experiences or isolated incidents are presented as proof. Pseudoscience, like ufology, often relies on such weak evidence (e.g., 'I saw a light in the sky'). True scientific practice involves rigorous hypothesis testing, data collection, and analysis, adhering to established methodologies like Occam's Razor to favor the simplest explanation.
