In 3–5 sentences, provide a statement that uses fallacious reasoning to make an argument. Then, explain how the fallacious reasoning weakens the argument and how it could be improved.

"Everyone knows that the Earth is flat because we can see a flat horizon when we look out at the ocean. Therefore, all scientific evidence claiming the Earth is round is wrong." This statement uses the fallacy of false consensus, assuming that because a certain belief is common, it must be true. To improve this argument, one must rely on actual scientific evidence and research rather than anecdotal observations.
