Then clearly there'd be a flaw with their method or reasoning. Say someone shows that there is a connection between Solar flares and migraines in humans on Earth, and concludes "fiat_money's life doesn't matter."; this would clearly be malformed conclusion or just their opinion. Therefore, the answer would be incorrect. Now, if instead, they show there is a connection between Solar flares and migraines in humans on Earth, then conclude that "Solar flares cause migraines in humans on Earth." and attribute this conclusion to the increased geomagneticism caused by the Solar flare; yet they also say "fiat_money's life doesn't matter.". It wouldn't mean that the latter statement is true simply because the first conclusion was derived scientifically and properly supported. So, technically, they'd be wrong.
If some hypothetical person decided to test that hypothetical conclusion, it'd be their hypothetical decision. Another hypothetical person could go about deciding to test a hypothetical Neo-Nazi singer's hypothetical conclusion that "Black people's lives don't matter" in the same manner. In either hypothetical example, the hypothetical outcome would be the product of the hypothetical person's actions; meaning neither example provides a valid argument against the profession of the the hypothetical persons who came up with the conclusion.
